PIP49_NN-term cysteine-rich ER, FAM69
|SMART accession number:||SM01299
||The FAM69 family of cysteine-rich type II transmembrane proteins localise to the endoplasmic reticulum (ER) in cultured cells, probably via N-terminal di-arginine motifs. These proteins carry at least 14 luminal cysteines which are conserved in all FAM69s. There are currently few indications of the involvement of FAM69 members in human diseases PMID:21334309. It would appear that FAM69 proteins are predicted to be have a protein kinase structure and function. Analysis of three-dimensional structure models and conservation of the classic catalytic motifs of protein kinases in four of human FAM69 proteins suggests they might have retained catalytic phosphotransferase activity. An EF-hand Ca2+-binding domain, inserted within the structure of the kinase domain, suggests they function as Ca2+-dependent kinases (unpublished).|
