• Observed Band(KD)：
• 40kD

• Background：
• Expression of this gene is induced by hexamethylene-bis-acetamide in vascular smooth muscle cells. This gene has no introns. [provided by RefSeq, Jul 2008],

• Function：
• domain:The coiled-coil domain mediates oligomerization.,function:Transcriptional regulator which functions as a general RNA polymerase II transcription inhibitor. In cooperation with 7SK snRNA sequesters P-TEFb in a large inactive 7SK snRNP complex preventing RNA polymerase II phosphorylation and subsequent transcriptional elongation. May also regulate NF-kappa-B, ESR1, NR3C1 and CIITA-dependent transcriptional activity.,induction:Up-regulated by HMBA (hexamethylene bisacetamide) (at protein level). Down-regulated by estrogen.,miscellaneous:Inhibits Tat activity which is required for HIV-1 transcription.,similarity:Belongs to the HEXIM family.,subcellular location:Binds alpha-importin and is mostly nuclear.,subunit:Homooligomer and heterooligomer with HEXIM2; probably dimeric. Component of the 7SK snRNP complex at least composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), HEXIM1, H

• Subcellular Location：
• Nucleus . Cytoplasm . Binds alpha-importin and is mostly nuclear (PubMed:16362050).

• Expression：
• Ubiquitously expressed with higher expression in placenta. HEXIM1 and HEXIM2 are differentially expressed. Expressed in endocrine tissues.
