Promotional Text:
Specificity:
This antibody recognizes Hexim1 at the N-terminus.
Molecular Weight:
53 kDa
Epitope:
N-terminus
Immunogen:
KLH-conjugated linear peptide corresponding to human Hexim 1 at and around the N-terminus.
Background Information:
Hexim1 is a transcriptional regulator which functions as a general RNA polymerase II transcription inhibitor. Hexim1 works in cooperation with 7SK snRNA to sequester P-TEFb in a large inactive 7SK snRNP complex, preventing RNA polymerase II phosphorylation and subsequent transcriptional elongation. The 7SK snRNP complex is composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), Hexim1, Hexim2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs. Hexim1 also interacts with the N-CoR complex through NCOR1, ESR1, NR3C1, and may interact with NF-kappa-B through REL A. Hexim1 is located in the nucleus where it can bind with alpha-importin, and can also be found in the cytoplasm. Hexim1 is up-regulated by HMBA (hexamethylene bisacetamide) at the protein level and down-regulated by estrogen.

UniProt Summary:
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.
SUBUNIT STRUCTURE: Homo-oligomer and hetero-oligomer with HEXIM2; probably dimeric. Component of the 7SK snRNP complex at least composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), HEXIM1, HEXIM2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs. Interacts with the N-CoR complex through NCOR1. Interacts with ESR1 and NR3C1. May interact with NF-kappa-B through RELA.
SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note: Binds alpha-importin and is mostly nuclear.
TISSUE SPECIFICITY: Ubiquitously expressed with higher expression in placenta. HEXIM1 and HEXIM2 are differentially expressed. Expressed in endocrine tissues.
INDUCTION: Up-regulated by HMBA (hexamethylene bisacetamide) (at protein level). Down-regulated by estrogen.
DOMAIN: The coiled-coil domain mediates oligomerization.
MISCELLANEOUS: Inhibits Tat activity which is required for HIV-1 transcription.
SEQUENCE SIMILARITIES: Belongs to the HEXIM family.
