FKBP8 Polyclonal Antibody

catalytic activity:Peptidylproline (omega=180) = peptidylproline (omega=0).,caution:It is uncertain whether Met-1 or Met-58 is the initiator.,cofactor:Calcium.,function:Constitutively inactive PPiase, which becomes active when bound to calmodulin and calcium. Seems to act as a chaperone for BCL2, targets it to the mitochondria and modulates its phosphorylation state. The BCL2/FKBP8/calmodulin/calcium complex probably interferes with the binding of BCL2 to its targets. The active form of FKBP8 may therefore play a role in the regulation of apoptosis.,miscellaneous:Binds the immunosuppressant FK506 only in its calmodulin/calcium activated form.,sequence caution:The first part of the cDNA maps to the same locus, but in opposite orientation.,similarity:Contains 1 PPIase FKBP-type domain.,similarity:Contains 3 TPR repeats.,subunit:Homomultimers or heteromultimers (Potential). Forms heterodimer with calmodulin. When activated by calmodulin and calcium, interacts with the BH4 domain of BCL2 and weakly with BCLX isoform Bcl-X(L). Does not bind and inhibit calcineurin. Interacts with HCV NS5A.,tissue specificity:Widely expressed. Highest levels seen in the brain.,
