Genomic imprinting is an epigenetic regulation that leads to gene expression in a
parent-of-origin specific manner. AFF3, the central component of the Super
Elongation Complex-like 3 (SEC-L3), is enriched at both the
intergenic-differentially methylated region (IG-DMR) and the Meg3 enhancer within
the imprinted Dlk1-Dio3 locus to regulate the allele-specific gene expression in
this locus. The localization of AFF3 to IG-DMR requires ZFP57. However, how AFF3
functions at the Meg3 enhancer in maintaining allele-specific gene expression
remains unclear. Here, we demonstrate that AFF3 is associated with the
Krüppel-like zinc finger protein ZFP281 in mouse embryonic stem (ES) cells.
ZFP281 recruits AFF3 to the Meg3 enhancer within the imprinted Dlk1-Dio3 locus,
thus regulating the allele-specific expression of the Meg3 polycistron. Our
genome-wide analyses further identify ZFP281 as a critical factor generally
associating with AFF3 at enhancers and functioning together with AFF3 in
regulating the expression of a subset of genes. Our study suggests that different
zinc finger proteins can recruit AFF3 to different regulatory elements and
differentially regulate the function of AFF3 in a context-dependent manner.
