Overview
AID Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation, gene conversion, and class- switch recombination in B-lymphocytes. Required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses. May also play a role in the epigenetic regulation of gene expression by participating in DNA demethylation. Strongly expressed in lymph nodes and tonsils. Belongs to the cytidine and deoxycytidylate deaminase family. Note: This description may include information from UniProtKB.
Protein type: Hydrolase; EC 3.5.4.5
Cellular Component: cytoplasm; exosome (RNase complex); nucleus
Molecular Function: protein binding; zinc ion binding; cytidine deaminase activity
Biological Process: somatic diversification of immunoglobulins; B cell differentiation; somatic hypermutation of immunoglobulin genes; isotype switching; cytidine deamination; mRNA processing
Reference #:  Q9GZX7 (UniProtKB)
Alt. Names/Synonyms: Activation-induced cytidine deaminase; AICDA; AID; ARP2; CDA2; Cytidine aminohydrolase; HIGM2; integrated into Burkitt's lymphoma cell line Ramos
Gene Symbols: AICDA
Molecular weight: 23,954 Da
Basal Isoelectric point: 9.5  Predict pI for various phosphorylation states
