The alignment shows four conserved cysteine residues and a conserved tryptophan. It was first identified by [1], and is predicted to be a "highly specialised mononuclear four-cysteine zinc finger...that plays a role in DNA binding and/or promoting protein-protein interactions in complicated eukaryotic processes including ...chromatin methylation status and early embryonic development." Weak homology to Pfam:PF00628 further evidences these predictions (personal obs: C Yeats). Twelve different CW-domain-containing protein subfamilies are described, with different subfamilies being characteristic of vertebrates, higher plants and other animals in which these domain is found [1].

Arabidopsis microrchidia (MORC) ATPase family proteins are conserved among plants and animals and are involved in transcriptional silencing. In Arabidopsis, MORC6/DMS11 was reported to function in the condensation of pericentromeric heterochromatin, thereby facilitating transcriptional silencing [1]. Further studies demonstrate that MORC6 and its homologs MORC1 and MORC2 form a complex which associates with SUVH9, required for Pol V occupancy in the RdDM (RNA-directed DNA methylation) pathway [2].
