Summary: Enables G-protein alpha-subunit binding activity and GDP-dissociation inhibitor activity. Predicted to be involved in several processes, including maintenance of centrosome location; microtubule cytoskeleton organization involved in mitosis; and regulation of spindle organization. Located in lateral cell cortex. Is expressed in several structures, including 2-cell stage conceptus; gonad; lung; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in sensorineural hearing loss. Orthologous to human GPSM2 (G protein signaling modulator 2). [provided by Alliance of Genome Resources, Dec 2024]

Mutation of the mouse orthologue of GPSM2 affects actin-rich stereocilia elongation in auditory and vestibular hair cells, causing deafness and balance defects. Gpsm2 defines an approximately 200 nm nanodomain at the tips of stereocilia and this localization requires the presence of Galphai3, myosin 15 and whirlin. Loss of Gpsm2 leads to decreased outgrowth and a disruption of actin dynamics in neuronal growth cones.

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.
