Chromosome | 1 | NCBI Gene Number | 14270 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables GTPase activator activity; protein homodimerization activity; and small GTPase binding activity. Involved in several processes, including filopodium assembly; nervous system development; and positive regulation of GTPase activity. Located in cytosol; phagocytic vesicle; and postsynaptic membrane. Is active in dendritic spine; glutamatergic synapse; and postsynaptic density. Is expressed in several structures, including central nervous system; dorsal root ganglion; heart; and sensory organ. Orthologous to several human genes including SRGAP2 (SLIT-ROBO Rho GTPase activating protein 2). PHENOTYPE: Mice homozygous for a hypomorphic gene trap allele are born at below the expected Mendelian ratio, but are otherwise viable. Layer 5 cortical pyramidal neurons exhibit an increased density of dendritic spines with a decreased spine head width and increased length of spine necks. [provided by MGI curators] |
