Summary: Enables guanyl-nucleotide exchange factor activity. Involved in Rac protein signal transduction; enzyme-linked receptor protein signaling pathway; and positive regulation of skeletal muscle acetylcholine-gated channel clustering. Predicted to be located in cytoplasmic side of plasma membrane; cytosol; and dendrite. Predicted to be active in glutamatergic synapse. Predicted to be extrinsic component of postsynaptic membrane. Is expressed in lung epithelium; nephron; nervous system; and retina. Orthologous to human FARP1 (FERM, ARH/RhoGEF and pleckstrin domain protein 1).

What's a GeneRIF?

It was shown that Farp1 regulates dendritic filopodial dynamics in immature neurons. Later in development, Farp1 is postsynaptic and FARP1's 4.1 protein/ezrin/radixin/moesin domain binds SynCAM 1, assembling a synaptic complex.
Title: The novel synaptogenic protein Farp1 links postsynaptic cytoskeletal dynamics and transsynaptic organization.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
