SCL-interrupting locus protein (STIL)

Immediate-early gene. Plays an essential role in embryonic development as well as in cellular growth and proliferation; its long-term silencing affects cell survival and cell cycle distribution in addition to decreases CDK1 activity correlated with reduced phosphorylation of CDK1.

Plays a role as a positive regulator of the sonic hedgehog pathway, acting downstream of PTCH1 (PubMed:16024801, PubMed:9372240). Plays an essential role in the regulation of centriole duplication.
