A PF01426 BAH BAH domain Domain This domain has been called BAH (Bromo adjacent homology) domain and has also been called ELM1 and BAM (Bromo adjacent motif) domain. The function of this domain is unknown but may be involved in protein-protein interaction [3]. PFAM PF01426
A PF00145 DNA_methylase C-5 cytosine-specific DNA methylase Domain PFAM PF00145
A PF02008 zf-CXXC CXXC zinc finger domain Domain This domain contains eight conserved cysteine residues that bind to two zinc ions. The CXXC domain is found in a variety of chromatin-associated proteins. This domain binds to nonmethyl-CpG dinucleotides. The domain is characterised by two repeats [3], and shows a peculiar internal duplication in which the second unit is inserted into the first one [4]. Each of these units is characterised by four conserved cysteines, displaying a CXXCXXCX(n)C motif that chelate a Zn+2 ion. The DNA binding interface has been identified by NMR [3]. In eukaryotes, the CXXC domain is found in stramenopiles, plants and metazoans. Plants possess a mono-CXXC domain that is present in distinct chromatin proteins [4]. Structural comparisons show that the mono-CXXC is homologous to the structural-zinc binding domain of medium chain dehydrogenases [4]. PFAM PF02008
A PF01426 BAH BAH domain Domain This domain has been called BAH (Bromo adjacent homology) domain and has also been called ELM1 and BAM (Bromo adjacent motif) domain. The function of this domain is unknown but may be involved in protein-protein interaction [3]. PFAM PF01426
