RCC1 domain-containing protein 1 (RCCD1)

Acts as a coregulator of KDM8 to promote histone demethylase activity on di- and trimethylated 'Lys-36' (H3K36me2/me3) of histone H3 (PubMed:24981860). Plays a role in transcriptional repression of satellite repeats, possibly by regulating H3K36 methylation levels in centromeric regions together with KDM8 (PubMed:24981860).

Possibly together with KDM8, involved in proper mitotic spindle organization and chromosome segregation (PubMed:24981860). Plays a role in regulating alpha- tubulin deacetylation and cytoskeletal microtubule stability and thereby promoting cell migration and TGF-beta-induced epithelial to mesenchymal transition (EMT), possibly through the inhibition of KDM8 (PubMed:28455245).
