Synonym
GFR alpha like, GFR alpha-like, GFRAL, GRAL
Source
Human GFR alpha-like, His Tag (GFA-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ser 19 - Glu 351 (Accession # Q6UXV0-1).
Predicted N-terminus: Ser 19
Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 39.7 kDa. The protein migrates as 43-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.

Background
GFR alpha-like is also known as GDNF family receptor alpha-like, GFRAL, C6orf144, UNQ9356, PRO34128. Growth differentiation factor-15 (GDF15) is a circulating protein that has been implicated in multiple biological processes, including energy homeostasis, body weight regulation, and cachexia driven by cancer and chronic disease. GDNF family receptor α-like (GFRAL) was recently identified as the neuronal brainstem receptor responsible for mediating the anorectic actions of GDF15. Brainstem-restricted receptor for GDF15 which regulates food intake, energy expenditure and body weight in response to metabolic and toxin-induced stresses . Upon interaction with its ligand, GDF15, interacts with RET and induces cellular signaling through activation of MAPK- and AKT- signaling pathways.
