This study isolated a novel splice variant of alpha-actinin 4 (skipping exons 3-12; ENST00000424234) that is predominantly localized in the nucleus, a pattern distinct from the full-length alpha-actinin 4, which is primarily distributed in the cytoplasm and plasma membrane. Exon 3: HsaEX6094930, ex 4: HsaEX6094929, ex 5: HsaEX6094928, ex 6: HsaEX6094927, ex 7: HsaEX6094926, ex 8: HsaEX0002154, ex 9: HsaEX7010513, ex 10: HsaEX1002558, ex 11: HsaEX6094925, ex 12: HsaEX6094924.

ACTN4(Iso) overexpression increases transcriptional activity of the VDRE and ERE promoters. Both ACTN4(WT) and ACTN4(Iso) co-immunoprecipitate with estrogen receptors. Overexpression of ACTN4(Iso) fused to Gal4 increases basal transcription. The same is seen with overexpression of ACTN4(WT)-Gal4, but the effect is smaller.

Overexpression of either ATN4(WT) or ACTN4(Iso) increases GRE reporter activity. Disruption of the LXXLL nuclear receptor-interacting motif present in ACTN4 results in reduced GR interaction and dexamethasone-mediated transactivation of a GRE reporter while still maintaining its actin-binding activity. In contrast, an ACTN4 isoform, ACTN4 (Iso), that loses its actin-binding domain is still capable of potentiating a GRE reporter.
