Attachment proteins anchor the cell membrane in various ways. Some attachment proteins bind the plasma membrane to the network of protein filaments within the cytoplasm called the cytoskeleton. The attachments between plasma membrane proteins and the underlying protein filaments produce the characteristic shapes of animal cells, from the dimpled discs of red blood cells to the elaborate branching of nerve cells. other membrane attachment proteins bind the cell to a matrix of other protein fibers that exist outside the cell. Still other attachment proteins form junctions between adjacent cells. .13 is a wonderful thing. lolz.
What else can I help you with?
What are the functions of attachment proteins that attach to specific receptors on cells?
Attachment proteins play a crucial role in attaching to specific receptors on cells, facilitating cell communication, signaling, and interactions. They help cells recognize and bind to each other, promoting cell adhesion, migration, and organization within tissues. Additionally, attachment proteins can also mediate immune responses, regulate cell growth and differentiation, and contribute to the overall stability and function of cells in the body.
What interlocks with a molecular shape in a host cell's plasma membrane?
Proteins on the surface of a virus interlock with specific receptor proteins on the host cell's plasma membrane. This interaction is crucial for the virus to gain entry into the host cell and initiate its replication cycle.
What is the type of cell attachment that resembles quilting with proteins acting as stitches?
The type of cell attachment that resembles quilting with proteins acting as stitches is called hemidesmosomes. Hemidesmosomes are specialized cell junctions found in epithelial tissues that anchor cells to the underlying basement membrane through intermediate filaments interacting with transmembrane proteins like integrins and collagen. This anchoring provides structural support and stability to the tissue.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
Where does the attachment of a mRNA molecule to a ribosome take place?
The attachment of a mRNA molecule to a ribosome takes place in the cytoplasm of a cell. The ribosome binds to the mRNA at the start codon to initiate protein synthesis. This process is essential for translating the genetic information encoded in the mRNA into a specific protein.
What are the external proteins used for attachment called?
the answer is fimbriae -shannon
What is an ankyrin?
An ankyrin is any of a family of adaptor proteins which mediate the attachment of integral membrane proteins to the spectrin-actin based membrane skeleton.

What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
What is the type of cell attachment that resembles quilting with proteins acting as stitches?
The type of cell attachment that resembles quilting with proteins acting as stitches is called hemidesmosomes. Hemidesmosomes are specialized cell junctions found in epithelial tissues that anchor cells to the underlying basement membrane through intermediate filaments interacting with transmembrane proteins like integrins and collagen. This anchoring provides structural support and stability to the tissue.
Which proteins are not synthesised in the ROUGH ER?
Proteins not synthesized in the rough endoplasmic reticulum (RER) include cytosolic proteins, which are synthesized by free ribosomes in the cytosol, as well as mitochondrial and plastid proteins, which are synthesized by ribosomes located within those organelles. Additionally, some nuclear proteins are also synthesized in the cytoplasm before being imported into the nucleus. Secreted proteins and membrane-bound proteins are typically synthesized in the RER due to ribosome attachment.
What are the spikes and there function in a virus?
Spikes are proteins that are part of the viral capsid/envelope (depending on if the virus is a naked virus or not). It helps with attachment to the host cell. They are derived from their host cell's own proteins (but are not the same as their hosts), and can help in evading the host cell's defenses.

The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
What are attachment sites called?
Attachment sites are commonly referred to as "binding sites" or "receptor sites." These are specific locations on proteins or cells where other molecules, such as ligands or substrates, can attach. In the context of biology, these sites are crucial for processes like signal transduction, enzyme activity, and cellular interactions.
What is covalent modification?
Covalent modification refers to the attachment of chemical groups, such as phosphate or methyl groups, to proteins to regulate their activity, localization, or stability. This type of modification can alter the functional properties of proteins by affecting their structure and interactions with other molecules. Examples include phosphorylation and acetylation.
What is a sentence for attachment?
The attachment has become loose.His attachment to me is a bit creepy.
