Recombinant Human C->U-editing enzyme APOBEC-1 (APOBEC1)

Uniprot Id

P41238

Target Species

Human

Target Name

APOBEC1

Target Full Name

C->U-editing enzyme APOBEC-1

Target Function

Catalytic component of the apolipoprotein B mRNA editing enzyme complex which is responsible for the postranscriptional editing of a CAA codon for Gln to a UAA codon for stop in the APOB mRNA. Also involved in CGA (Arg) to UGA (Stop) editing in the NF1 mRNA. May also play a role in the epigenetic regulation of gene expression by participating in DNA demethylation.

Target Subcellular Location

Cytoplasm.

Target Protein Families

Cytidine and deoxycytidylate deaminase family

Target Tissue Specificity

Expressed exclusively in the small intestine.

Target Synonyms

ABEC1_HUMAN; APOBEC 1; APOBEC1; Apolipoprotein B mRNA editing enzyme; Apolipoprotein B mRNA editing enzyme catalytic polypeptide 1; Apolipoprotein B mRNA editing enzyme complex 1; Apolipoprotein B mRNA-editing enzyme 1; BEDP; C->U-editing enzyme APOBEC-1; CDAR1; EC 3.5.4.; HEPR

Target Background

This gene encodes a member of the cytidine deaminase enzyme family. The encoded protein forms a multiple-protein editing holoenzyme with APOBEC1 complementation factor (ACF) and APOBEC1 stimulating protein (ASP). This holoenzyme is involved in the editing of C-to-U nucleotide bases in apolipoprotein B and neurofibromatosis-1 mRNAs. Multiple transcript variants encoding different isoforms have been found for this gene.
