      DescriptionAnti-RBL2 Antibody
      Alternate Names
      • 130 kDa retinoblastoma-associated protein
      • retinoblastoma-like 2 (p130)
      Background InformationRBL2, retinoblastoma-like protein 2 also referred to as a pocket protein, belongs to the RB family of tumor suppressors, as does another pocket protein p107. These pocket proteins are involved in cell proliferation, differentiation, and transformation. They also share a significant amount of sequence homology. RBL2 is an important regulator of entry in cell division and may act as a transcription repressor by recruiting chromatin-modifying enzymes to promoters.

      UniProt Number
      UniProt SummaryFUNCTION: Key regulator of entry into cell division. Directly involved in heterochromatin formation by maintaining overall chromatin structure and, in particular, that of constitutive heterochromatin by stabilizing histone methylation. Recruits and targets histone methyltransferases SUV420H1 and SUV420H2, leading to epigenetic transcriptional repression. Controls histone H4 'Lys-20' trimethylation. Probably acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. Potent inhibitor of E2F-mediated trans-activation, associates preferentially with E2F5. Binds to cyclins A and E. Binds to and may be involved in the transforming capacity of the adenovirus E1A protein. May act as a tumor suppressor.

      SIZE: 1139 amino acids; 128367 Da

      SUBUNIT: Interacts with AATF. Interacts with SUV420H1 and SUV420H2 (By similarity). Interacts with RINT1.


      PTM: During G0 and early G1 phase of the cell cycle, phosphorylated on Ser-639 and on 5 sites within the domain B. Phosphorylation on Ser-672 in G1 leads to its ubiquitin-dependent proteolysis.

      SIMILARITY: Belongs to the retinoblastoma protein (RB) family.

      MISCELLANEOUS: G0-restricted expression.
