Protein Structure
UniProt Annotation
Function May coordinately regulate cell cycle progression and transcription during spermatogenesis. Inhibits degradation of polyubiquitinated cyclin A and cyclin B1 and thereby arrests the cell cycle at early M phase. ESXR1-N acts as a transcriptional repressor. Binds to the sequence 5'-TAATGTTATTA-3' which is present within the first intron of the KRAS gene and inhibits its expression. ESXR1-C has the ability to inhibit cyclin turnover. {ECO:0000269PubMed:15235584, ECO:0000269PubMed:15897875}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:15235584}. Nucleus {ECO:0000255PROSITE-ProRule:PRU00108, ECO:0000269PubMed:15235584}. Note=ESXR1-N localizes specifically to the nucleus while ESXR1-C localizes specifically to the cytoplasm.
Disease Associations
Tissue Specificity Expressed in placenta and testis. Expressed in testicular germ cell tumors. {ECO:0000269PubMed:11374906, ECO:0000269PubMed:15235584}.
