PA1-053 detects leptin (OB-R) from human, mouse, and rat tissues. PA1-053 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~100 kDa and ~125 kDa protein representing the short and long forms of OB-R from mouse brain extract. This antibody also detects two smaller, unrelated proteins of ~31 kDa and 35 kDa which are unable to be competed with the peptide in mouse liver extract. The PA1-053 immunogen is a synthetic peptide corresponding to residues K(577) E I Q W K T H E V F D A K S K S A(594) of the extracellular domain of rat OB-R. This sequence is completely conserved in mouse OB-R. PA1-053 immunizing peptide (Cat. No. PEP-014) is available for use in neutralization and control experiments.

The leptin (OB-R) receptor is a member of the cytokine receptor superfamily which plays an important role in mammalian body weight homeostasis and energy balance. Ligand-induced activation of the OB-R by the adipose tissue-secreted hormone, leptin, appears to activate downstream signaling events through the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. Leptin can homo-dimerize OB-R extracellular domains while downstream signaling events are initiated upon homo-dimerization of OB-R intracellular domains. Several isoforms of the OB-R which differ in length and signaling capabilities have been reported. RNA transcripts encoding the OB-R long form have been found in the choroid plexus and in the hypothalamus which has been proposed as a control center for satiety and energy expenditure. Mutations in either the mouse OB-R (db) or leptin (ob) genes have been shown to result in early-onset obesity. Metabolic abnormalities attributable to these genotypes include hypercorticoidemia, hyperinsulinemia and insulin resistance, hyperglycemia, altered CNS activity, reduced metabolic rate of brown adipose tissue, and a large increase in white adipose tissue.
