      DescriptionAnti-Hexim 2 Antibody
      Alternate Names
      • Hexamethylene bis-acetamide-inducible protein 2
      • MAQ1 paralog
      • hexamethylene-bis-acetamide-inducible transcript 2
      • hexamthylene bis-acetamide inducible 2
      Background InformationRegulates transcription by acting as a general inhibitor of RNA polymerase II. Similar to HEXIM1, HEXIM2 forms a complex with p-TEFb and 7SK that prevents p-TEFb from activating transcriptional elongation. When HEXIM1 is knocked down, HEXIM2 functionally compensates for its association with P-TEFb. HEXIM2 is up-regulated by HMBA (hexamethylene bisacetamide) at protein level.

      UniProt Number
      UniProt SummaryFUNCTION: 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.

      SUBUNIT STRUCTURE: Homo-oligomer and heterooligomer with HEXIM1; 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.


      TISSUE SPECIFICITY: Ubiquitously expressed with higher expression in testis. HEXIM1 and HEXIM2 are differentially expressed.

      INDUCTION: Up-regulated by HMBA (hexamethylene bisacetamide) (at protein level).

      DOMAIN: The coiled-coil domain mediates oligomerization.

      SEQUENCE SIMILARITIES: Belongs to the HEXIM family.
