Descriptions

Plexin cell surface receptors bind to semaphorin ligands and transduce signals for regulating neuronal axon guidance. In mouse Plexin-A3 (P70208), the autoinhibitory regions including an Rho GTPase-binding domain (RBD) and a segment preceding C1 domain make extensive interactions with the GAP domain (C1 and C2 domains), which may enable it to regulate the GAP conformation in response to semaphorin binding. According to human Plexin-A1 (Q9UIW2) study, the Sema domain in Plexin-A3 may be also involved in autoinhibition.

5 GO annotations of cellular component

Name Definition
integral component of plasma membrane The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
lamellipodium A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments.
lamellipodium membrane The portion of the plasma membrane surrounding a lamellipodium.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
semaphorin receptor complex A stable binary complex of a neurophilin and a plexin, together forming a functional semaphorin receptor.

2 GO annotations of molecular function

Name Definition
protein domain specific binding Binding to a specific domain of a protein.
semaphorin receptor activity Combining with a semaphorin, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

19 GO annotations of biological process

Name Definition
angiogenesis Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.
aorta development The progression of the aorta over time, from its initial formation to the mature structure. An aorta is an artery that carries blood from the heart to other parts of the body.
branching involved in blood vessel morphogenesis The process of coordinated growth and sprouting of blood vessels giving rise to the organized vascular system.
cardiac septum development The progression of a cardiac septum over time, from its initial formation to the mature structure.
coronary vasculature development The process whose specific outcome is the progression of the blood vessels of the heart over time, from its formation to the mature structure.
dichotomous subdivision of terminal units involved in salivary gland branching The process in which a salivary epithelial cord bifurcates at its end.
endothelial cell migration The orderly movement of an endothelial cell into the extracellular matrix to form an endothelium.
kidney development The process whose specific outcome is the progression of the kidney over time, from its formation to the mature structure. The kidney is an organ that filters the blood and/or excretes the end products of body metabolism in the form of urine.
negative regulation of cell adhesion Any process that stops, prevents, or reduces the frequency, rate or extent of cell adhesion.
outflow tract morphogenesis The process in which the anatomical structures of the outflow tract are generated and organized. The outflow tract is the portion of the heart through which blood flows into the arteries.
positive regulation of axonogenesis Any process that activates or increases the frequency, rate or extent of axonogenesis.
positive regulation of protein binding Any process that activates or increases the frequency, rate or extent of protein binding.
regulation of angiogenesis Any process that modulates the frequency, rate or extent of angiogenesis.
regulation of cell migration Any process that modulates the frequency, rate or extent of cell migration.
regulation of cell shape Any process that modulates the surface configuration of a cell.
regulation of GTPase activity Any process that modulates the rate of GTP hydrolysis by a GTPase.
semaphorin-plexin signaling pathway The series of molecular signals generated as a consequence of a semaphorin receptor (composed of a plexin and a neurophilin) binding to a semaphorin ligand.
semaphorin-plexin signaling pathway involved in axon guidance Any semaphorin-plexin signaling pathway that is involved in axon guidance.
synapse assembly The aggregation, arrangement and bonding together of a set of components to form a synapse. This process ends when the synapse is mature (functional).
