SRGAP2 Antibody – Rabbit Polyclonal

This locus encodes a member of the SLIT-ROBO Rho GTPase activating protein family. This human-specific locus resulted from incomplete segmental duplication of the SLIT-ROBO Rho GTPase activating protein 2 locus. The encoded protein lacks the GTPase activating protein domain compared to proteins encoded by SLIT-ROBO Rho GTPase activating protein 2. The functionality of the protein encoded by this locus has been questioned, as several normal individuals with homozygous deletions for this locus have been identified, and the expression of this locus appears to be much lower than the similar SLIT-ROBO Rho GTPase activating protein 2C (SRGAP2C) locus. The SRGAP2C locus has been shown to encode a protein that functions antagonistically to SLIT-ROBO Rho GTPase activating protein 2 in cortical neuron development. [provided by RefSeq, Dec 2012]

SRGAP2C: Involved in dendritic spine maturation through interaction with and inhibition of SRGAP2. Reduces the rate of spine maturation and indirectly increases neuronal migration. Changes dendritic spine morphology and density and may have implications for cognition, learning and memory. Homodimer. Interacts with SRGAP2; formation of the heterodimer alters SRGAP2 function

Chromosomal Location of Human Ortholog: 1p11.2

Molecular Function: protein homodimerization activity; protein heterodimerization activity

Biological Process: extension of a leading process involved in cell locomotion in cerebral cortex radial glia guided migration; negative regulation of filopodium formation
