ominmn2

Ominmn2 is a protein encoded by the ominmn2 gene, identified in diverse marine microbial genomes. It is predicted to be a small, membrane-associated protein of unknown function, and is considered part of a proposed family of transport-related membrane proteins common in bacteria.

Predicted features from computational analyses indicate multiple transmembrane segments, typically four to six, with conserved residues in cytoplasmic loops. No experimentally solved structure has been published, and subcellular localization is inferred from sequence signals to the inner membrane in gram-negative bacteria.

Function remains undetermined. Some comparative genomics studies suggest a role in ion or metabolite transport, or in redox-related processes, but biochemical validation is lacking. Its essentiality is not established, and phenotypic effects upon deletion or overexpression have not been consistently observed.

Evolution and distribution show Ominmn2 homologs across a wide range of bacterial lineages, with higher prevalence in marine and soil microbiomes. Genomic neighborhoods often include genes linked to metal homeostasis or energy metabolism, implying possible coordination within membrane-associated pathways.

Research status notes that Ominmn2 is a poorly characterized protein. Current work focuses on determining its structure, expression across environmental conditions, and any physiological roles. There are no known associations with human disease.
