Cleft lip and palate transmembrane protein 1 (Clptm1) is a multi-transmembrane protein that in humans is encoded by the CLPTM1 gene.{{cite journal | vauthors = Yoshiura K, Machida J, Daack-Hirsch S, Patil SR, Ashworth LK, Hecht JT, Murray JC | title = Characterization of a novel gene disrupted by a balanced chromosomal translocation t(2;19)(q11.2;q13.3) in a family with cleft lip and palate | journal = Genomics | volume = 54 | issue = 2 | pages = 231–240 | date = December 1998 | pmid = 9828125 | doi = 10.1006/geno.1998.5577 }}{{cite web | title = Entrez Gene: CLPTM1 cleft lip and palate associated transmembrane protein 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=1209}} Clptm1 was characterized in 1995 as a surface membrane protein in the thymus during embryonic development in mice and is suggested to have an important role in T-cell development.{{cite journal | vauthors = Takeuchi T, Kuro-o M, Miyazawa H, Ohtsuki Y, Yamamoto H | title = Transgenic expression of a novel thymic epithelial cell antigen stimulates aberrant development of thymocytes | journal = Journal of Immunology | volume = 159 | issue = 2 | pages = 726–733 | date = July 1997 | doi = 10.4049/jimmunol.159.2.726 | pmid = 9218588 }}{{cite journal | vauthors = Takeuchi T, Tamamoto T, Tamura H, Yamamoto H | title = Characterization of a 50 kDa surface membrane protein on thymic stromal cells as an important factor for early T cell development | journal = International Immunology | volume = 7 | issue = 4 | pages = 583–590 | date = April 1995 | pmid = 7547685 | doi = 10.1093/intimm/7.4.583 }} A more recent study shows a role in GABAA receptor subunit intracellular anchoring and regulation resulting in an influence on synaptic strength{{cite journal | vauthors = Ge Y, Kang Y, Cassidy RM, Moon KM, Lewis R, Wong RO, Foster LJ, Craig AM | display-authors = 6 | title = Clptm1 Limits Forward Trafficking of GABAA Receptors to Scale Inhibitory Synaptic Strength | journal = Neuron | volume = 97 | issue = 3 | pages = 596–610.e8 | date = February 2018 | pmid = 29395912 | doi = 10.1016/j.neuron.2017.12.038 | pmc = 5810584 }} Clptm1 belongs to a family of several eukaryotic cleft lip and palate transmembrane protein 1 sequences.
Cleft lip with or without cleft palate is a common birth defect that is genetically complex. The non-syndromic forms have been studied genetically using linkage and candidate-gene association studies with only partial success in defining the loci responsible for orofacial clefting. CLPTM1 encodes a transmembrane protein and has strong homology to two Caenorhabditis elegans genes, suggesting that CLPTM1 may belong to a new gene family.{{cite journal | vauthors = Yoshiura K, Machida J, Daack-Hirsch S, Patil SR, Ashworth LK, Hecht JT, Murray JC | title = Characterization of a novel gene disrupted by a balanced chromosomal translocation t(2;19)(q11.2;q13.3) in a family with cleft lip and palate | journal = Genomics | volume = 54 | issue = 2 | pages = 231–240 | date = December 1998 | pmid = 9828125 | doi = 10.1006/geno.1998.5577 }} This family also contains the Homo sapiens cisplatin resistance related protein CRR9p which is associated with CDDP-induced apoptosis.{{cite journal | vauthors = Yamamoto K, Okamoto A, Isonishi S, Ochiai K, Ohtake Y | title = A novel gene, CRR9, which was up-regulated in CDDP-resistant ovarian tumor cell line, was associated with apoptosis | journal = Biochemical and Biophysical Research Communications | volume = 280 | issue = 4 | pages = 1148–1154 | date = February 2001 | pmid = 11162647 | doi = 10.1006/bbrc.2001.4250 }}
