General description

The human GHRH (also known as GHRF) gene (Gene ID 2691) encodes the 108 aa Somatoliberin preproprotein (UniProt P01286; also known as GHRH, GRF, Growth hormone-releasing factor, Growth hormone-releasing hormone, INN: Sermorelin, Sermorelin, Somatocrinin, Somatorelin). Post-translatioinal removal of the signal peptide (aa 1-20) and the two propeptide sequences (aa 21-31 and aa 76-108) releases the 44 aa mature Somatoliberin (aa 32-75) that functions as a ligand to stimulate growth hormone (GH) release from the pituitary. Variant GHRH receptors are found in several types of tumors. Antagonists against such receptors are reported to inhibit tumors growth. Defects in GHRH gene cause dwarfism and hypersecretion of somatoliberin is linked to gigantism.

Specificity

Clone 1B4.2 is expected to detect prepro-, pro-, and mature somatoliberin.

Immunogen

Epitope: Mature somatoliberin
KLH-conjugated linear peptide corresponding to mature human somatoliberin sequence.

Application
