Display abstract
We report a novel protein domain-G8-which contains five repeated beta-strandpairs and is present in some disease-related proteins such as PKHD1, KIAA1199,TMEM2 as well as other uncharacterized proteins. Most G8-containing proteins are predicted to be membrane-integral or secreted. The G8 domain may be involved inextracellular ligand binding and catalysis. It has been reported that mis-sensemutations in the two G8 domains of human PKHD1 protein resulted in a less stable protein and are associated with autosomal-recessive polycystic kidney disease,indicating the importance of the domain structure. G8 is also present in theN-terminus of some non-syndromic hearing loss disease-related proteins such asKIAA1109 and TMEM2. Discovery of G8 domain will be important for the research of the structure/function of related proteins and beneficial for the development of novel therapeutics. Contact: liangsp@hunnu.edu.cn
