Relevance: Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation , gene conversion, and class-switch recombination in B-lymphocytes by deaminating C to U during transcription of Ig-variable and Ig-switch region DNA. 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.

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Function: Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation (SHM), gene conversion, and class-switch recombination (CSR) in B-lymphocytes by deaminating C to U during transcription of Ig-variable (V) and Ig-switch (S) region DNA. Required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses

Involvement in disease: Immunodeficiency with hyper-IgM 2 (HIGM2)

Subcellular Location: Nucleus, Cytoplasm

Protein Families: Cytidine and deoxycytidylate deaminase family

Tissue Specificity: Strongly expressed in lymph nodes and tonsils.

Paythway:

Form: Liquid or Lyophilized powder

Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
