WICH complex

An ISWI complex that contains an ATPase subunit of the ISWI family (specifically SNF2H in mammals, which contain two ISWI homologs) and WSTF (Williams Syndrome Transcription Factor). WICH plays roles in regulation of RNAP I and III transcription and in DNA replication and repair.

G protein-coupled opsin signaling pathway

A G protein-coupled receptor signaling pathway that starts with an opsin being activated by a photon, and ending with the light signal being trasmitted through the synapses. The signal can be transmitted via different Galpha subunits types: Go, Gs, Gq, and Gt.

obsolete WINAC complex

OBSOLETE. A SWI/SNF-type complex that directly interacts with the vitamin D receptor (VDR) through the Williams syndrome transcription factor (WSTF), and mediates the recruitment of unliganded VDR to VDR target sites in promoters. The WINAC complex contains at least 13 subunits, including WSTF, several SWI/SNF components, and DNA replication-related factors.
