Transmembrane protein 19 is a protein that in humans is encoded by the TMEM19 gene.
The TMEM19 gene is located on chromosome 12(12q21.1) spanning 18,966 base pairs on the + strand. The gene has a total of 6 exon regions.
Studies have found that after using single nucleotide polymorphism (SNP) genotyping array method the TMEM19 gene was identified to be associated with ammonia nitrogen tolerance. [5] Using a genome-wide association study of individuals with non-syndromic cleft lip with palate (NSCLP) to identify loci that are at risk for the birth defect. [6] From this they were able to identify the loci of TMEM19 as a risk for this birth defect, along with 25 other loci.
The mRNA transcript of TMEM19 is 5662 base pairs. The TMEM19 transcript was found to be expressed in most tissues but has increased expression in duodenum, kidney, skin, small intestine, and urinary bladder. in a non-alcoholic fatty liver disease (NAFLD) model in cells that were subjected to glucose deficiency or oxidative stress. This results in cell death due to excessive disulfide formation in actin cytoskeleton and actin filament called disulfidptosis. [7]
TMEM19 is a protein spanning 336 amino acids. It has 6 transmembrane regions. The protein is found at moderate levels in the body, with the highest expression found in superior cervical ganglia and cardiac myocytes. [10] TMEM19 interacts with many proteins, most of these proteins are localized around membranes found in the cell.
