It exists as two major isoforms (CASZ1a and CASZ1b) whose transcriptional activity depends critically on N-terminal zinc fingers 1–4 and an activation domain at aa 31–185 [PMID:16631614, PMID:22331471]. The CASZ1b N-terminus (aa 23–40) is bifunctional, serving as both a nuclear localization determinant and the docking site for the NuRD nucleosome-remodeling/histone-deacetylase corepressor complex, enabling HDAC-dependent epigenetic repression; CASZ1 also engages the polycomb repressive complex in a splice-variant-specific manner [PMID:26296975, PMID:27270431, PMID:30072429]. Through these activities CASZ1 controls chromatin accessibility, super-enhancer establishment, and histone modification at target loci to drive lineage programs—activating MYOD-pathway genes in skeletal muscle, promoting permissive marks at Th17 loci, establishing inverted heterochromatin organization in rod photoreceptors via lamin A/C suppression, and enforcing epidermal terminal differentiation downstream of p63 and p300 [PMID:26296975, PMID:30072429, PMID:29467767, PMID:32060262, PMID:38458428].

In endothelium CASZ1 directly activates EGFL7 to promote RhoA-dependent vascular assembly, and in the cochlea it consolidates inner hair cell fate by maintaining Gata3 [PMID:23639441, PMID:39883789].

It exists as two major isoforms (CASZ1a and CASZ1b) whose transcriptional activity depends critically on N-terminal zinc fingers 1–4 and an activation domain at aa 31–185 [#0, #3]. The CASZ1b N-terminus (aa 23–40) is bifunctional, serving as both a nuclear localization determinant and the docking site for the NuRD nucleosome-remodeling/histone-deacetylase corepressor complex, enabling HDAC-dependent epigenetic repression; CASZ1 also engages the polycomb repressive complex in a splice-variant-specific manner [#9, #11, #15]. Through these activities CASZ1 controls chromatin accessibility, super-enhancer establishment, and histone modification at target loci to drive lineage programs—activating MYOD-pathway genes in skeletal muscle, promoting permissive marks at Th17 loci, establishing inverted heterochromatin organization in rod photoreceptors via lamin A/C suppression, and enforcing epidermal terminal differentiation downstream of p63 and p300 [#9, #15, #16, #18, #22].
