UniProt functional annotation for Q6PJP8

UniProt code: Q6PJP8.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: May be required for DNA interstrand cross-link repair. Also required for checkpoint mediated cell cycle arrest in early prophase in response to mitotic spindle poisons. {ECO:0000269|PubMed:15542852}.
 
Subunit: Binds constitutively to TP53BP1. Binds CDC27, which is itself a component of the anaphase promoting complex (APC). Binds PIAS1.
Subcellular location: Nucleus {ECO:0000269|PubMed:10848582, ECO:0000269|PubMed:12446782, ECO:0000269|PubMed:15572677}. Note=In some cells it may be found in typically 1 or 2 discrete nuclear aggregates of unknown function which also contain TP53BP1. Also found in multiple discrete nuclear foci which increase in number following treatment with ionizing radiation or interstrand cross-linking agents. These foci overlap with those formed by the MRN complex (composed of MRE11, RAD50 and NBN) and BRCA1.
Tissue specificity: Expressed in brain, heart, kidney, liver, pancreas, placenta and skeletal muscle. {ECO:0000269|PubMed:12446782}.
Induction: During mitosis. The mRNA encoding this protein contains an internal ribosome entry site (IRES) in its 5'-UTR. This 5'-UTR generally suppresses translation while specifically promoting expression during mitosis, when cap-dependent translation may be impaired. {ECO:0000269|PubMed:12509242}.
Similarity: Belongs to the DNA repair metallo-beta-lactamase (DRMBL) family. {ECO:0000305}.
Sequence caution: Sequence=BAA07646.2; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
