Studies suggest glycan–glycan interactions, observed to be approximately 200–300 pN, also may play a role in cell–cell recognition. [4] Complex carbohydrates, in particular, have been studied to be extremely integral in cell–cell recognition, especially when it is recognized by complementary carbohydrates.
The name lectin is a bit misleading because the family includes proteins with at least one C-type lectin domain (CTLD) which is a specific type of carbohydrate recognition domain. CTLD is a ligand binding motif found in more than 1000 known proteins (more than 100 in humans) and the ligands are often not sugars. [ 17 ]
The MAPK protein is an enzyme, a protein kinase that can attach phosphate to target proteins such as the transcription factor MYC and, thus, alter gene transcription and, ultimately, cell cycle progression. Many cellular proteins are activated downstream of the growth factor receptors (such as EGFR) that initiate this signal transduction pathway.
Within the cell, they appear in the blood, the extracellular matrix, or on the outer surface of the plasma membrane, and make up a large portion of the proteins secreted by eukaryotic cells. [4] They are very broad in their applications and can function as a variety of chemicals from antibodies to hormones.

Signal recognition particle (SRP) receptor, also called the docking protein, is a dimer composed of 2 different subunits that are associated exclusively with the rough ER in mammalian cells. Its main function is to identify the SRP units.
Function [1] Pattern recognition receptors (PRRs) (e.g. TLRs, NLRs) Pathogen-associated molecular patterns (PAMP) Mediate cytokine production → inflammation → destroying pathogen: Killer activated and killer inhibitor receptors (KARs and KIRs) Avails NK cells to identify abnormal host cells (KAR) or inhibit inappropriate host cell ...
The ability of the immune system to recognize molecules that are broadly shared by pathogens is, in part, due to the presence of immune receptors called toll-like receptors (TLRs) that are expressed on the membranes of leukocytes including dendritic cells, macrophages, natural killer cells, cells of the adaptive immunity T cells, and B cells, and non-immune cells (epithelial and endothelial ...
