Also known as ARHGAP34, FNBP2, SRGAP2A, SRGAP3, SLIT-ROBO Rho GTPase activating protein 2

SLIT-ROBO Rho GTPase-activating protein 2 (srGAP2), also known as formin-binding protein 2 (FNBP2), is a mammalian protein that in humans is encoded by the SRGAP2 gene. It is involved in neuronal migration and differentiation and plays a critical role in synaptic development, brain mass and number of cortical neurons. Downregulation of srGAP2 inhibits cell–cell repulsion and enhances cell–cell contact duration.

Name
SLIT-ROBO Rho GTPase activating protein 2
Type
protein-coding
Aliases
ARHGAP34, FNBP2, SRGAP2A

This locus encodes a member of the SLIT-ROBO Rho GTPase activating protein family. The encoded protein stimulates GTPase activity of Rac1, and plays a role in cortical neuron development. This locus has several paralogs on human chromosome 1 resulting from segmental duplication. While this locus itself is conserved among various species, the paralogs are found only in the genus Homo, and not in the genomes of non-human great apes. Alternatively spliced transcript variants have been described for this locus. [provided by RefSeq, Jul 2014].

SLIT-ROBO Rho GTPase-activating protein 2 (srGAP2), also known as formin-binding protein 2 (FNBP2), is a mammalian protein that in humans is encoded by the SRGAP2 gene. It is involved in neuronal migration and differentiation and plays a critical role in synaptic development, brain mass and number of cortical neurons. Downregulation of srGAP2 inhibits cell–cell repulsion and enhances cell–cell contact duration.

SRGAP2 dimerizes through its F-BAR domain. SRGAP2C, a shortened version found in early hominins and humans that only has the F-BAR domain, antagonizes its action. It slows maturation of some neurons and increases neuronal spine density. SRGAP2 may also be involved in the development of some cancers.
