paa1Protein phosphatase PP2A regulatory subunit A; Phosphatase 2A affects a variety of biological processes in the cell such as transcription, cell cycle progression and cellular morphogenesis, and provides an initial identification of critical substrates for this phosphatase. The regulatory subunit may direct the catalytic subunit to distinct, albeit overlapping, subsets of substrates (By similarity). (590 aa)
apc11Anaphase-promoting complex subunit 11; Component of the anaphase-promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin-protein ligase complex that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C is thought to confer substrate specificity and, in the presence of ubiquitin-conjugating E2 enzymes, it catalyzes the formation of protein-ubiquitin conjugates that are subsequently degraded by the 26S proteasome. (94 aa)
tup12Transcriptional repressor tup12; Transcriptional repressor. (598 aa)
skp1Suppressor of kinetochore protein 1; Required for cig2 degradation in the G2 and M phases of the cell cycle. Together with pof6, essential for septum processing and cell separation. Involved in mitotic progression, essential for the execution of anaphase B; required for coordinated structural alterations of mitotic spindles and segregation of nuclear membrane structures at anaphase. Involved in the DNA damage checkpoint pathway and maintenance of genome integrity. Component of the RAVE complex which is required for stable assembly of the vacuolar ATPase complex V- ATPase. Belongs to th [...] (161 aa)
orc4Origin recognition complex subunit 4; Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. ORC binds to multiple sites within the ars1 origin of DNA replication in an ATP-independent manner. This binding is mediated by the N-terminal A.T hook repeats of orc4. (972 aa)
cnd2Condensin complex subunit 2; Regulatory subunit of the condensin complex, a complex required for conversion of interphase chromatin into mitotic-like condense chromosomes. The condensin complex probably introduces positive supercoils into relaxed DNA in the presence of type I topoisomerases and converts nicked DNA into positive knotted forms in the presence of type II topoisomerases. The condensin complex probably also plays a role during interphase in processes such as DNA repair. Belongs to the CND2 (condensin subunit 2) family. (742 aa)
