Harmonizome 3.0

plexin C1

This gene encodes a member of the plexin family. Plexins are transmembrane receptors for semaphorins, a large family of proteins that regulate axon guidance, cell motility and migration, and the immune response. The encoded protein and its ligand regulate melanocyte adhesion, and viral semaphorins may modulate the immune response by binding to this receptor. The encoded protein may be a tumor suppressor protein for melanoma. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Jan 2011]

plexin D1

Enables protein domain specific binding activity. Predicted to be involved in several processes, including positive regulation of axonogenesis; semaphorin-plexin signaling pathway; and synapse assembly. Predicted to act upstream of or within circulatory system development; dichotomous subdivision of terminal units involved in salivary gland branching; and kidney development. Located in lamellipodium. [provided by Alliance of Genome Resources, Mar 2025]

plexin A3

This gene encodes a member of the plexin class of proteins. The encoded protein is a class 3 semaphorin receptor, and may be involved in cytoskeletal remodeling and as well as apoptosis. Studies of a similar gene in zebrafish suggest that it is important for axon pathfinding in the developing nervous system. This gene may be associated with tumor progression.

plexin A2

This gene encodes a member of the plexin-A family of semaphorin co-receptors. Semaphorins are a large family of secreted or membrane-bound proteins that mediate repulsive effects on axon pathfinding during nervous system development. A subset of semaphorins are recognized by plexin-A/neuropilin transmembrane receptor complexes, triggering a cellular signal transduction cascade that leads to axon repulsion. This plexin-A family member is thought to transduce signals from semaphorin-3A and -3C. [provided by RefSeq, Jul 2008]

plexin A1

Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell; nervous system development; and positive regulation of axonogenesis. Predicted to act upstream of or within dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection extension; and regulation of smooth muscle cell migration. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Mar 2025]

plexin A4

Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including nervous system development; positive regulation of axonogenesis; and semaphorin-plexin signaling pathway. Predicted to act upstream of or within nervous system development; regulation of axon extension involved in axon guidance; and regulation of negative chemotaxis. Predicted to be located in membrane. Predicted to be part of semaphorin receptor complex. Predicted to be active in cerebellar climbing fiber to Purkinje cell synapse and plasma membrane.

plexin B2

Members of the B class of plexins, such as PLXNB2 are transmembrane receptors that participate in axon guidance and cell migration in response to semaphorins (Perrot et al. (2002) [PubMed 12183458]).[supplied by OMIM, Mar 2008]

plexin B3

The protein encoded by this gene is a member of the plexin family. It functions as a receptor for semaphorin 5A, and plays a role in axon guidance, invasive growth and cell migration. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

plexin B1

Enables semaphorin receptor activity. Involved in several processes, including negative regulation of cell adhesion; regulation of cell shape; and semaphorin-plexin signaling pathway. Located in plasma membrane. Part of semaphorin receptor complex. [provided by Alliance of Genome Resources, Mar 2025]

plexin domain containing 2

Predicted to be located in membrane. [provided by Alliance of Genome Resources, Mar 2025]

plexin domain containing 1

Predicted to be involved in angiogenesis. Part of receptor complex. [provided by Alliance of Genome Resources, Mar 2025]
