**Background of GOAT Recombinant Protein**
Ghrelin O-acyltransferase (GOAT) is a key enzyme responsible for the post-translational modification of ghrelin, a peptide hormone primarily produced in the stomach. GOAT catalyzes the octanoylation of ghrelin at serine-3. a critical step required for ghrelin's activation of the growth hormone secretagogue receptor (GHSR). This acylation enables ghrelin to regulate essential physiological processes, including appetite stimulation, energy homeostasis, and growth hormone release. Dysregulation of the ghrelin-GOAT system has been implicated in metabolic disorders such as obesity, diabetes, and cachexia.
The development of recombinant GOAT protein emerged as a pivotal tool for studying ghrelin biology and its therapeutic targeting. Recombinant GOAT is typically produced using heterologous expression systems (e.g., mammalian cells, bacteria, or insect cells) engineered to express the human or murine GOAT gene. Purification often involves affinity chromatography tags for high yield and specificity. Its availability has accelerated structural studies (e.g., crystallography) to elucidate enzyme-substrate interactions and inhibitor-binding mechanisms.
Research using recombinant GOAT has highlighted its potential as a drug target. Small-molecule inhibitors of GOAT, designed using recombinant protein-based assays, show promise in preclinical models for curbing obesity and metabolic syndrome by suppressing active ghrelin levels. Additionally, recombinant GOAT facilitates biomarker studies linking ghrelin signaling to diseases like Prader-Willi syndrome and cancer-associated wasting.
Despite challenges in mimicking its native membrane-bound environment *in vitro*, recombinant GOAT remains indispensable for mechanistic studies and drug discovery, offering insights into metabolic regulation and therapeutic innovation.
