APOBEC1 complementation factor is a protein that in humans is encoded by the A1CF gene.^[5]^[6]^[7]

Gene

Alternative splicing occurs at this locus and three full-length transcript variants, encoding three distinct isoforms, have been described. Additional splicing has been observed but the full-length nature of these variants has not been determined.^[7]

Function

Mammalian apolipoprotein B mRNA undergoes site-specific C to U deamination, which is mediated by a multi-component enzyme complex containing a minimal core composed of APOBEC1 and a complementation factor encoded by this gene.^[8] The gene product has three non-identical RNA recognition motifs and belongs to the hnRNP R family of RNA-binding proteins. It has been proposed that this complementation factor functions as an RNA-binding subunit and docks APOBEC1 to deaminate the upstream cytidine. Studies suggest that the protein may also be involved in other RNA editing or RNA processing events.^[7]

Its deletion results in lethality in mice.^[9]

Interactions

A1CF has been shown to interact with APOBEC1,^[10]^[11] CUGBP2,^[12] and SYNCRIP.^[13]^[10]
