      Background InformationAgo2 (argonaute-2), also known as eukaryotic translation initiation factor 2C (EIF2C2), is an essential component for siRNA-directed RNA interference (RNAi) response. Ago2 is an endonuclease required for the unwinding of siRNA duplex and assembly of siRNA into RNA-induced silencing complexes (RISC). Ago2 interacts with DICER1 through its Piwi domain. This Piwi domain is thought to provide RNA cleavage activity via a mechanism similar to RNase H. Ago2 activity is necessary for embryonic development as well as RNA-mediated gene silencing (RNAi).

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, and contains a PAZ domain and a PIWI domain. It may interact with dicer1 and play a role in short-interfering-RNA-mediated gene silencing.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P45973 # Component of heterochromatin. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Can interact with lamin B receptor (LBR). This interaction can contribute to the association of the heterochromatin with the inner nuclear membrane. Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins.
      SIZE: 191 amino acids; 22225 Da
      SUBUNIT: Interacts with SUV420H1 and SUV420H2 (By similarity). Interacts directly with ATRX, CHAF1A, LBR, NIPBL, SP100, STAM2 and TRIM28 via the chromoshadow domain. Can interact directly with CBX3 via the chromoshadow domain. Interacts with histone H3 methylated at 'Lys-9'. Interacts with MIS12 and C20orf127.
      SUBCELLULAR LOCATION: Nucleus. Centromere. Note=Component of centromeric and pericentromeric heterochromatin. Associates with chromosomes during mitosis. Associates specifically with chromatin during metaphase and anaphase.
      PTM: Phosphorylation of HP1 and LBR may be responsible for some of the alterations in chromatin organization and nuclear structure which occur at various times during the cell cycle (By similarity). Phosphorylated during interphase and possibly hyper- phosphorylated during mitosis.
      SIMILARITY: SwissProt: P45973 ## Contains 2 chromo domains.
