Uses
Anti-APOBEC3A antibody produced in rabbit has also been used in immunofluorescence staining.
General Description
The gene APOBEC3A (apolipoprotein B mRNA editing enzyme catalytic subunit 3A) is mapped to human chromosome 22q13.1. The protein has a catalytically active deaminase domain. It belongs to the APOBEC3 genes family.
Biochem/physiol Actions
APOBEC3A (apolipoprotein B mRNA editing enzyme catalytic subunit 3A) is a cytidine deaminase. APOBEC3 proteins are mainly involved in intracellular antiviral defense responses, particularly against retroviruses. They are also involved in carcinogenesis by dC (deoxycytidine) deamination, thereby causing DNA mutations. APOBEC3A also exhibits mRNA-editing function. It is involved with guanine-to-alanine editing in transcripts of WT1 (wilms tumor 1). Deletion in APOBEC3A gene is associated with breast cancer predisposition. This happens due to increased stability of APOBEC3A mRNA.
