ocm4

This is the community wiki page for the gene ocm4 please feel free to add any information that is relevant to this gene that is not already captured elsewhere in Xenbase.

nomenclature updates

05JUNE 2023 Xenopus gene symbol changed from ocm4.1 to ocm4, to symplify synax and avoid compuational issues/problems caused by the .1 suffix.

synteny and orthology notes

X. tropicalis (as well as coelocanth and bony fish) have larger tandem arrays of OCM genes, specifically the OCM4 paralogues

The gene symbols used for the tandem genes in this cluster are correct according to NCBI/Ref Seq (see discussion logged RSCOM-81).

<CCZ1 <OCM1 <OCM4.6 <OCM4.5 <OCM4.4 <OCM4.3 <OCM4.2 <OCM4.1 <OCM3 LMTK2>

NCBI REfseq tream agree with "Xenbase .. correctly names the gene adjacent to CCZ1 as OCM1 and ... properly name the gene adjacent to LMTK2 as OCM3".

OCM3 has no orthologs in placental mammals but has orthologs in chicken NP_001007478.1, platypus XP_001512095.1, and opossum XP_007498332.1.

The single OCM3 gene is related to a tandem cluster of genes Xenbase has named OCM4.1-OCM4.6.

OCM4 has no orthologs in mammals but is orthologous to chicken XP_025011090.1.
