Descriptions

PlexA1 (NOV, PLXN1) plays a role in axon guidance, invasive growth and cell migration. Sema domain of PlexA1 restricts PlexA1 to a basal inactive state by binding to the remainder of the ectodomain. Deletion analysis of the PlexinA1 ectodomain demonstrates that the sema domain prevents PlexinA1 activation in the basal state. Sema-deleted PlexinA1 is constitutively active, producing cell contraction, growth cone collapse, and inhibition of neurite outgrowth. Plexin A1 is autoinhibited by its sema domain, and Sema3A/NP1 releases this inhibition. According to mouse Plexin-A3 (P70208), Plexin may possess a segment preceding C1 domain and an RDB domain as autoinhibitory elements.

3 GO annotations of cellular component

Name Definition
membrane A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
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.

1 GO annotations of molecular function

Name Definition
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.

8 GO annotations of biological process

Name Definition
axon guidance The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
axonal defasciculation Separation of axons away from a bundle of axons known as a fascicle.
morphogenesis of a branching structure The process in which the anatomical structures of branches are generated and organized. A branch is a division or offshoot from a main stem. Examples in animals would include blood vessels, nerves, lymphatics and other endothelial or epithelial tubes.
negative regulation of cell adhesion Any process that stops, prevents, or reduces the frequency, rate or extent of cell adhesion.
positive regulation of axonogenesis Any process that activates or increases the frequency, rate or extent of axonogenesis.
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.
semaphorin-plexin signaling pathway involved in axon guidance Any semaphorin-plexin signaling pathway that is involved in axon guidance.
