Summary: The protein encoded by this gene is a member of the centaurin GTPase family. This gene product regulates the activity of multiple kinases, including PI3K. Reduced expression of this gene results in multiple defects, including neural deficiencies, while increased expression of this gene has been observed in some tumors. Alternative splicing results in multiple protein isoforms. [provided by RefSeq, Jul 2014]

Dopamine and DOPAC were not changed in 3-mo-old mice but were decreased at 8 mo in the striatum of PIKE-KO mice compared with wild-type mice. DA and DOPAC in hippocampus and substantia nigra were significantly decreased in 3-mo-old and 8-mo-old PIKE-KO mice as compared with wild-type mice. More severe motor defects in PIKE-KO and Fyn-KO mice than in wild-type mice exposed to alpha synuclein and MPTP.

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.
