OPA1-15411 detects the melanocortin 4 receptor (MC4R) from human samples.
OPA1-15411 has been successfully used in immunohistochemistry procedures. By immunohistochemistry, OPA1-15411 detects the melanocortin 4 receptor (MC4R) in formalin fixed, paraffin embedded human tissues.
The OPA1-15411 immunogen is a synthetic peptide (KLH conjugated) to the N-terminus.
Expression of MC4R has been reported in brain. Unlike the other melanocortin receptors, MC4R is not expressed in adrenal cortex or in melanocytes.
G-protein Coupled Receptors (GPCRs) comprise one of the largest families of signaling molecules with more than a thousand members currently predicted to exist. All GPCRs share a structural motif consisting of seven membrane-spanning helices, and exist in both active and inactive forms. An array of activating ligands participate in the conformation of GPCRs which leads to signaling via G-proteins and downstream effectors. Ongoing studies have also shown the vast series of reactions which participate in the negative regulation of GPCRs. This "turn-off" activity has tremendous implications for the physiological action of the cell, and continues to drive pharmacological research for new drug candidates. Two blockbuster drugs which have been developed as GPCR-targeted pharmaceuticals are Zyprexa (Eli Lilly) and Claritin (Schering-Plough) which have multi-billion dollar shares of the mental health and allergy markets, respectively.
