FKBP7

FK506 binding protein 7 is a protein that in humans is encoded by the FKBP7 gene. ^[1] The gene is also known as FKBP23 and PPIase. ^[1] FKBP7 belongs to the FKBP-type peptidyl-prolyl cis/trans isomerase (PPIase) family. Members of this family exhibit PPIase activity and function as molecular chaperones. The orthologous protein in mouse is located in the endoplasmic reticulum and binds calcium. ^{[1] [2]}

Model organisms

Model organisms have been used in the study of FKBP7 function. A conditional knockout mouse line, called Fkbp7^{tm2a(KOMP)Wtsi [3] [4]} was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute. ^{[5] [6] [7]}

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. ^{[8] [9]}
