Function

SCM3_YEAST Centromeric protein that plays a central role in the incorporation and maintenance of histone H3-like variant CENPA at centromeres.[UniProtKB:Q8NCD3]CENPA_YEAST Histone H3-like variant which exclusively replaces conventional H3 in the nucleosome core of centromeric chromatin at the inner plate of the kinetochore. Required for recruitment and assembly of kinetochore proteins, mitotic progression and chromosome segregation.

Required for functional chromatin architecture at the yeast 2-micron circle partitioning locus and promotes equal plasmid segregation.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] H4_YEAST
