Tumor suppressor functions of MCPH1/BRIT1 and BRCA1; links with the inactivation of the functional form of hTERT and the activation of dominant negative splice variants of hTERT. PMID: 29860064
MCPH1 interacts with and promotes the E3 ligase betaTrCP2 to degrade Cdc25A independent of DNA damage. Overexpression of betaTrCP2 or the knockdown of Cdc25A remedies the high mitotic index and rescues the premature differentiation of Mcph1-deficient neuroprogenitors in vivo MCPH1 itself is degraded by APC/CCdh1, but not APC/CCdc20, in late mitosis and G1 phase.
