CHL4/YDR254W Summary Help

Standard Name CHL4 1, 2
Systematic Name YDR254W
Alias CTF17 3 , MCM17 4
Feature Type ORF, Verified
Description Outer kinetochore protein required for chromosome stability; involved in new kinetochore assembly and sister chromatid cohesion; forms a stable complex with Iml3p; peripheral component of the Ctf19 kinetochore complex that interacts with Ctf19p, Ctf3p, and Mif2p; required for the spindle assembly checkpoint; orthologous to human centromere constitutive-associated network (CCAN) subunit CENP-N and fission yeast mis15 (5, 6, 7, 8, 9, 10, 11, 12)
