Protein-coding gene in the species Homo sapiens

Transmembrane protein 222 is a protein that in humans is encoded by the TMEM222 gene.[5][6] One notable feature of the protein encoded by this gene is the presence of three predicted transmembrane domains.[7] The TMEM222 protein is predicted to most likely localize to the secretory vesicles.[8]

Gene Features[edit]

TMEM222 has a domain of unknown function (DUF778).[9] Aliases of this gene include DKFZP564D0478, RP11-4K3__A.4, C1orf160, and MGC111002.[10] Accession NM_032125.2, the longest coding sequence (1629 bp), encodes a protein of 208 amino acid residues (23230 Daltons), which is considered the consensus coding sequence (CCDS297.2).[11] There are two isoforms of the protein encoded by this gene. They are similar except the second (Q9H0R3-2) is lacking the first 96 amino acid residues that are present in the first (Q9H0R3-1).[12]

Gene Expression[edit]

ACEVIEW has labeled TMEM222 as highly expressed with 3.8 times more expression than the average gene in the database.[13] There is expression evidence from 166 tissues including brain, lung, colon, kidney, and placenta.[13]

Homology[edit]

Orthologs and distant homologs of the human TMEM222 have been identified throughout Eukaryota especially in plants and animals.[14] No paralogs of this gene have been found in the human genome.[15]

Distant Homolog[edit]

A distant homolog of TMEM222,[14] RTH (RTE1-Homolog),[16] is a homolog of RTE1 (Reversion-to-Ethylene Perception 1), which is known to induce conformational changes in ETR1 (Ethylene receptor 1) that result in negative regulation corresponding with loss of ethylene perception.[17]

Protein Interactions[edit]

Evidence from yeast two-hybrid screening exists for two protein interactions with this gene. One is a serine protease (PRSS23)[18] that has been identified to be involved in mouse ovulation and is excreted into the extracellular matrix.[19] The other protein is an ab-hydrolase (HLA-B associated transcript 5)[20] that is integral to the membrane, and its corresponding gene is located in the genome near Tumor Necrosis Factor (TNF)-alpha and TNF-beta.[21]
