>cd04103 Centaurin_gamma Centaurin gamma. The centaurins (alpha, beta, gamma, and delta) are large, multi-domain proteins that all contain an ArfGAP domain and ankyrin repeats, and in some cases, numerous additional domains. Centaurin gamma contains an additional GTPase domain near its N-terminus. The specific function of this GTPase domain has not been well characterized, but centaurin gamma 2 (CENTG2) may play a role in the development of autism. Centaurin gamma 1 is also called PIKE (phosphatidyl inositol (PI) 3-kinase enhancer) and centaurin gamma 2 is also known as AGAP (ArfGAP protein with a GTPase-like domain, ankyrin repeats and a Pleckstrin homology domain) or GGAP. Three isoforms of PIKE have been identified. PIKE-S (short) and PIKE-L (long) are brain-specific isoforms, with PIKE-S restricted to the nucleus and PIKE-L found in multiple cellular compartments. A third isoform, PIKE-A was identified in human glioblastoma brain cancers and has been found in various tissues.
