产品介绍 background:
This gene encodes a dual-function 65 kDa protein that undergoes proteolytic cleavage to produce a 45 kDa N-terminal fragment with a paired-like homeodomain and a 20 kDa C-terminal fragment with a proline-rich domain. 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]

Function:
May coordinay 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.

Subcellular Location:
Cytoplasm. Nucleus. ESXR1-N localizes specifically to the nucleus while ESXR1-C localizes specifically to the cytoplasm.

Tissue Specificity:
Expressed in placenta and testis. Expressed in testicular germ cell tumors.

Post-translational modifications:
Undergoes proteolytic cleavage; produces a 45 kDa N-terminal homeodomain-containing fragment (ESXR1-N) and a 20 kDa C-terminal fragment (ESXR1-C).
