Description :Rabbit Polyclonal Antibody
Specificity :Recognizes the ALK7protein
Cited Applications :WB, ELISA
Cross Reactivity :Human, Mouse and Rat
Host / Isotype / Clone# :Rabbit, IgG
Immunogen :ALK7 antibody was raised against a 15 amino acid synthetic peptide near the amino terminus of the human ALK7
Purification :Affinity chromatography
Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
Sample Data :Western blot analysis of ALK7 in human placenta tissue lysate with ALK7 antibody at (A) 1 and (B) 2 ug/ml.
Scientific Background :ALK7 is a type I receptor for the TGFB family of signaling molecules in which type I receptors phosphorylate cytoplasmic SMAD transcription factors, which then translocate to the nucleus and interact directly with DNA or in complex with other transcription factors (1). Alk7 was expressed in all insulin, glucagon, and somatostatin -positive cells of the pancreas (2). GDF3 regulates adipose tissue homeostasis and energy balance under nutrient overload, in part, by signaling through ALK7 and Alk7 showed reduced fat accumulation and partial resistance to diet-induced obesity, similar to Gdf3.
