11 genes broken down into 5 alpha (LAMA), 3 beta (LAMB), 3 gamma (LAMC). From them there are multiple different splice isoforms however the only major different forms are alpha3a and alpha3b which use alternate promoters to generate two dramatically different polypeptides. The 11 genes give rise to ~15 different laminin heterotrimers, each comprised one alpha, one beta and one gamma chain with tissue/cell type/developmental stage specific expression patterns. The ~ reflects the fact that while many heterotrimers have been isolated some are not fully characterized and may be artifacts of isolation.

Approximately how many proteins in the human body are estimated to function as transcription factors?
Around 2000 proteins are involved in the regulation of genes in the developing cell in a human body, though there is an estimated 2600 DNA binding proteins, but only around the 2000 is required to account for regulating all the genes in each of our genome during development. its about 10% of the total protein information we have in our genes because the human genome contains information to approx. 25000 proteins.
Why are important proteins?
they are complex macromolecules that carry out many functions in the body including: growth and repair, signaling from one cell to another, defense against invaders, and catalyzing chemical reactions. human bodies couldn't function without proteinsProteins are important for many biological function in the cells. Proteins like collagen, actin, tubulin, myosin build up the body. Functional protein such as hormones, transporters, enzymes carry out many diverse role in cells.
How many aminos acids are there?
There are 21 amino acids found in the human body used to synthesize proteins, one of which can not be created directly by the human body. This is called Selenocysteine, and is found in eukaryotes. There is a 22nd amino acide, Pyrrolysine, which is used by some methanogenic archaea. There are many others, but these 22 are the only ones essential to life.
How many epiglottis in the human body?
There is one epiglottis in the human body.
Does the human body contain nitrogen?
Yes, all organisms need nitrogen because part of the nucleotides of nucleic acids (DNA and RNA) is a "nitrogeneous base", which is essential for life. Nitrogen is also present in many organic compounds, including proteins and nucleic acids. By mass nitrogen is the 4th most abundant element in the body.
How many proteins exist in the human body?
There are estimated to be tens of thousands of different proteins in the human body.
How does proteins get digested in human body?
Pepsin starts digestion of proteins by breaking down the many of polypeptides into shorter peptides.
What kind of polymer is built from amino acids in the human body?
Proteins are polymers built from amino acids in the human body. Proteins are essential macromolecules that have many important functions in the body, including catalyzing biochemical reactions, providing structural support, and serving as signaling molecules.
How can you eat cow muscle protein if you only have human proteins in your body?
All proteins are made up of chains of amino acids, the building blocks for protein. When you eat "cow muscle protein," your body breaks the proteins down into amino acids, which are absorbed in the small intestine and then utilized for your body to produce the proteins that we require. Many proteins, however are identical in the cow and human. (i.e. actin and myosin, two proteins that allow for muscle contraction)
How many proteins in a human being?
Considering the human body has an astronomical amount of protein types and each protein type has an astronomical number of individual proteins, pin-pointing a number is worthless. Your body creates and loses proteins constantly. There are only 4 major types for DNA: adenine, cytosine, guanine and thymine. As for a # of proteins as a whole: A whole bunch.
How many genes are present in human body?
There are estimated to be 26000 genes after completing the human genome project.
What is function of proteins?
There are many functions of proteins. They are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues. The human body is about one half muscle, and muscles are mostly made of proteins. There are seven main types of protein: antibodies, contractile proteins, enzymes, hormonal proteins, storage proteins, structural proteins, and transport proteins.
Approximately how many proteins in the human body are estimated to function as transcription factors?
Around 2000 proteins are involved in the regulation of genes in the developing cell in a human body, though there is an estimated 2600 DNA binding proteins, but only around the 2000 is required to account for regulating all the genes in each of our genome during development. its about 10% of the total protein information we have in our genes because the human genome contains information to approx. 25000 proteins.
What are the various uses of proteins in the human body?
Proteins in the human body have many important functions, including building and repairing tissues, supporting immune function, acting as enzymes for chemical reactions, and serving as hormones for communication between cells. They also play a role in muscle contraction, transportation of molecules, and maintaining the body's structure and integrity.
How many bonds are in the human body?
There are many different types of bonds in the human body, including covalent bonds, ionic bonds, and hydrogen bonds. These bonds play key roles in maintaining the structure and function of biological molecules such as proteins, DNA, and carbohydrates.
How many bones in the human body How many muscles in the human body?
there are 600 muscles in the human body and there are,206 bones in the body
In the human body where does sulfur come from?
Sulfur in the human body comes from dietary sources like proteins and amino acids. It is incorporated into sulfur-containing molecules such as cysteine and methionine, which are essential for various biological processes including protein structure and enzyme function. Sulfur is also a component of vitamins such as biotin and thiamine.
