BIR1
L000004754, YJR089W
Subunit of chromosomal passenger complex (CPC); CPC is comprised of Ipl1p-Sli15p-Bir1p-Nbl1p and regulates chromosome segregation; required for chromosome bi-orientation and for spindle assembly checkpoint activation upon reduced sister kinetochore tension; relative distribution to shortened microtubules increases upon DNA replication stress; sumoylated in an Mms21p-dependent manner; human survivin homolog

CEP1, CPF1, CP1, L000000311, L000000401, YJR060W
Basic helix-loop-helix (bHLH) protein; forms homodimer to bind E-box consensus sequence CACGTG present at MET gene promoters and centromere DNA element I (CDEI); affects nucleosome positioning at this motif; associates with other transcription factors such as Met4p and Isw1p to mediate transcriptional activation or repression; associates with kinetochore proteins, required for chromosome segregation; protein abundance increases in response to DNA replication stress

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
Publication
Participation of Bir1p, a member of the inhibitor of apoptosis family, in yeast chromosome segregation events.
Yeast two-hybrid and genetic interaction screens indicate that Bir1p, a yeast protein containing phylogenetically conserved antiapoptotic repeat domains called baculovirus inhibitor of apoptosis repeats (BIRs), is involved in chromosome segregation events. In the two-hybrid screen, Bir1p specifically interacts with Ndc10p, an essential component of the yeast kinetochore. Although Bir1p carries two BIR motifs in the N-terminal region, the C-terminal third ... [more]
