| 1312433 | LACTB | lactamase beta | This gene encodes a mitochondrially-localized protein that has sequence similarity to prokaryotic beta-lactamases. Many of the residues responsible for beta-lactamase activity are not conserved in this protein, suggesting it may have a different enzymatic function. Increased expression of the relate d mouse gene was found to be associated with obesity. Alternative splicing results in multiple transcript variants encoding different protein isoforms.
