Spindlin interactor and repressor of chromatin-binding protein (Spindoc)

Negatively regulates the transcriptional activator activity of SPIN1 via inhibition of its histone methyl-binding ability. Represses the expression of a number of SPIN1-regulated genes as well as the SPIN1-mediated activation of the Wnt signaling pathway (PubMed:29061846).

Can also inhibit the histone methyl- binding abilities of SPIN2A, SPIN2B, SPIN3 and SPIN4 (By similarity). .
