The C-terminal fragment localizes to the cytoplasm while the N-terminal fragment localizes exclusively to the nucleus. In contrast to human, the mouse homolog has a novel PN/PF motif in the C-terminus and is paternally imprinted in placental tissue. This gene likely plays a role in placental development and spermatogenesis. [provided by RefSeq, Jan 2010]. * **UniProt Summary**: 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:0000269|PubMed:15235584, ECO:0000269|PubMed:15897875}. |Homeobox| |DNA-binding transcription repressor activity, RNA polymerase II-specific| |RNA polymerase II regulatory region sequence-specific DNA binding| |nuclear speck| |sequence-specific DNA binding| |negative regulation of transcription by RNA polymerase II| |regulation of cell cycle| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |DNA-binding transcription factor activity, RNA polymerase II-specific| |negative regulation of gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp399|Salubrinal 20μM R07 exp399]]|-1.97| |[[:results:exp341|BRD2 inhibitor II 20μM R07 exp341]]|-1.95| |[[:results:exp380|NMS-873 0.07μM R07 exp380]]|-1.85| |[[:results:exp185|L-BMAA 500 to 750μM on day4 R04 exp185]]|1.82| |[[:results:exp190|Vincristine 0.0005μM R04 exp190]]|1.82| |[[:results:exp242|Radicicol 0.16μM R05 exp242]]|1.83| |[[:results:exp61|YM155 0.0002μM R01 exp61]]|1.95| No correlation found to any other genes in chemogenomics.
