拮抗凋亡转录因子抗体
品名:
拮抗凋亡转录因子抗体
货号:
hj-1126A
英文:
Anti-AATF antibody
英文缩写:
AATF

产品介绍background:
The protein encoded by this gene was identified on the basis of its interaction with MAP3K12/DLK, a protein kinase known to be involved in the induction of cell apoptosis. This gene product contains a leucine zipper, which is a characteristic motif of transcription factors, and was shown to exhibit strong transactivation activity when fused to Gal4 DNA binding domain. Overexpression of this gene interfered with MAP3K12 induced apoptosis.

Function:
May function as a general inhibitor of the histone deacetylase HDAC1. Binding to the pocket region of RB1 may displace HDAC1 from RB1/E2F complexes, leading to activation of E2F target genes and cell cycle progression. Conversely, displacement of HDAC1 from SP1 bound to the CDKN1A promoter leads to increased expression of this CDK inhibitor and blocks cell cycle progression. Also antagonizes PAWR mediated induction of aberrant amyloid peptide production in Alzheimer disease (presenile and senile dementia), although the molecular basis for this phenomenon has not been described to date.

Subunit:
Binds PAWR, POLR2J, RB1/RB, RBL1/P107, RBL2/P130, and SP1. May also bind MAPT.

Subcellular Location:
Nucleus, nucleolus.

Tissue Specificity:
Ubiquitously expressed. Expressed at high levels in brain, heart, kidney, placenta and thymus.

Post-translational modifications:
Hyperphosphorylated during the G1/S phase transition.

Similarity:
Belongs to the AATF family.
