General description
Orexin B consists of an amidated C-terminus and shares 46% sequence identity with orexin-A, mainly in the C-terminal region. Orexin-B is proteolytically cleaved from the precursor prepro-orexin.
Biochem/physiol Actions
Orexin-A and Orexin-B are orexigenic peptides that mediate their effects via two receptors, the orexin-1 receptor (OX1R) and the orexin-2 receptor (OX2R). Orexins are involved in food intake, obesity regulation, energy homeostasis, and differentiation.

The neuropeptides orexin A and B (also known as hypocretins) play an important role in many physiological and behavioral activities. Orexins are ligands of two closely related G-protein-coupled receptors, that are the named orexin 1 and orexin 2 receptors. To

Orexin-A and orexin-B, via their receptors orexin-1 receptor (OX1R) and orexin-2 receptor (OX2R) have been shown to play a role in the regulation of feeding, body weight, and energy expenditure. Adipose tissue also contributes significantly to the maintenance of body
