this protein and E2F4 interact with tumor suppressor proteins p130 and p107, but not with pRB involved in the initiation of eukaryotic genome replication transcription factor that regulates cell cycle progression, apoptosis and cellular transformation gene targets encodes a subunit of the condensin complex, which is responsible for the condensation and stabilization of chromosomes during mitosis and meiosis member of BCL-2 family, which act as anti- or pro-apoptotic regulators;

plays a major role in the G1/S transition by regulating topoisomerase II alpha and retinoblastoma gene expression, and functions in the p53-dependent DNA damage checkpoint part of the origin recognition complex (ORC), it binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors such as origin recognition complex. Cdc6 and Mcm proteins; gene subunit 6 like (yeast) silencing studies with small interfering RNA demonstrated that this protein plays an essential role in coordinating chromosome replication and segregation with cytokinesis protein tyrosine phosphatase, functions in the regulation of receptor type, F RAD21 HR21 RAD21 homolog (S. pombe) HIST1H4C H4FG histone cluster 1, H4c HSPE1 HSP10 heat shock 10kDa protein 1 (chaperonin 10) PBK SPK PDZ binding kinase epithelial cell-cell contacts at adherents junctions and in the control of beta-catenin signaling highly regulated association of this protein with mitotic chromatin specifically at the centromere region suggests its role in sister chromatid cohesion in mitotic cells this gene is intronless and encodes a member of the histone H4 family; transcripts from this gene lack polyA tails but instead contain a palindromic termination element gene encodes a major heat shock protein which functions as a chaperonin encodes a serine/threonine kinase related to the dual specific mitogenactivated protein kinase kinase (MAPKK) family; this mitotic kinase may be involved in the activation of lymphoid cells and support testicular functions, with a suggested role in the process of spermatogenesis
