Functioni

MCH may act as a neurotransmitter or neuromodulator in a broad array of neuronal functions directed toward the regulation of goal-directed behavior, such as food intake, and general arousal.1 Publication

Post-translational modificationi

Pro-MCH is processed differentially in the brain and in peripheral organs producing two neuropeptides; NEI and MCH. A third peptide, NGE, may also be produced. Preferential processing in neurons by prohormone convertase 2 (PC2) generates NEI. MCH is generated in neurons of the lateral hypothalmic area by several prohormone convertases including PC1/3, PC2 and PC5/6.1 Publication

Expressioni

Tissue specificityi

Predominantly expressed in hypothalamus. Also found in heart, intestine, spleen and testis (spermatogonia, early spermatocytes and Sertoli cells). In brain only mature MCH and NEI peptides are present. In peripheral tissues a large product, encompassing the NEI and MCH domains of the precursor, is found predominantly.1 Publication

Developmental stagei

Expression is enhanced between postnatal days 10 and 15.
