特异性

Clone 5L18 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects ULK1 phosphorylated on serine 757.

免疫原

KLH-conjugated linear peptide corresponding to 13 amino acids surrounding phosphoserine 757 from the C-terminal half of human ULK1.

应用

Peptide Inhibition Assay: Target band detection in lysate from serum starved A431 cells was prevented by preblocking of a representative lot (1:1,000 dilution) with the immunogen phosphopeptide, but not the corresponding non-phosphopeptide.
Affinity Binding Assay: A representative lot of this antibody bound phosphorylated ULK1 (pSer757) peptide with a KD of 8.2 x 10-6 in an affinity binding assay.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Anti-phospho-ULK1-Ser757, clone 5L18 ZooMAb, Cat. No. ZRB1621, is a recombinant Rabbit monoclonal antibody that targets ULK1 phosphorylated on serine 757 and is tested in Affinity Binding Assay and Peptide Inhibition Assay, and Western Blotting.

目标描述

Serine/threonine-protein kinase ULK1 (UniProt: O75385; also known as EC:2.7.11.1, Autophagy-related protein 1 homolog, ATG1, hATG1, Unc-51-like kinase 1) is encoded by the ULK1 (also known as KIAA0722) gene (Gene ID: 8408) in human. ULK1 is a ubiquitously expressed serine-threonine protein kinase that is involved in autophagy in response to starvation. During starvation it is localized to puncate structures primarily representing the isolation membrane that sequesters a portion of the cytoplasm resulting in the formation of an autophagosome. In cells, ULK1 is constitutively in complex with at least three proteins: ATG13, FIP200 and ATG101. Interaction of ULK1 with ATG13 or FIP200 is reported to increase ULK1 kinase activity and stability. ULK1 undergoes autophosphorylation under nutrient-rich conditions and is dephosphorylated during starvation or following treatment with rapamycin. Under nutrient sufficiency, it is phosphorylated by MTOR/mTOR, which disrupts the interaction with AMPK and prevents activation of ULK1. In response to nutrient limitation it is phosphorylated and activated by AMPK that leads to activation of autophagy. It can also act as a regulator of AMPK by mediating phosphorylation of AMPK subunits PRKAA1, PRKAB2 and PRKAG1, leading to negatively regulation of AMPK activity. Under nutrient sufficiency, high mTOR activity is reported to prevent ULK1 activation by phosphorylating ULK1 on serine 757 and disrupt its interaction with AMPK. The protein kinase domain of ULK1 is localized to amino acids 16-278. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
