Protein Information (annotations from UniProt)

Database IDHIV0000555
UniProt IDQ69YH5
Primary gene name(s)CDCA2
Synonym gene name(s)unknown
Protein nameCell division cycle-associated protein 2
Protein functionRegulator of chromosome structure during mitosis required for condensin-depleted chromosomes to retain their compact architecture through anaphase. Acts by mediating the recruitment of phopsphatase PP1-gamma subunit, PPP1CC to chromatin at anaphase and into the following interphase. At anaphase onset, its association with chromatin targets a pool of PPP1CC to dephosphorylate substrates. {ECO:0000269|PubMed:16492807, ECO:0000269|PubMed:16998479}.
Subcellular locationNucleus {ECO:0000269|PubMed:16492807}. Note=Excluded from the nucleolus. Present in nucleoplasm throughout the G1, S and G2 stages of the cell cycle. During M phase, it becomes diffuse throughout the cell as the nuclear membrane breaks down, and faintly accumulates later on metaphase chromatin. As the cell progresses to anaphase, it accumulates on chromatin.
