Anti-Dok1 (Ser-450), Phosphospecific Antibody (WB, E)

Name: Anti-Dok1 (Ser-450), Phosphospecific Antibody
Brand: PhosphoSolutions
SKU: DP2181
Price: 329.0 USD
Availability: InStock

Our Dok1 (Ser-450) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Dok1 (Ser-450) and is antigen affinity purified. It is great for use in WB.

Western blot image of Jurkat cells stimulated with calyculin A (100 nM, 30 min) (lanes 1-6) followed by lambda phosphatase (lanes 2 & 6) or alkaline phosphatase (lane 4) treatment. The blots were probed with anti-Dok1 (lanes 1 & 2), anti-Dok1 (Tyr-362) (lanes 3 & 4), and anti-Dok1 (Ser-450) (lanes 5 & 6).

Target

Dok1 (Ser-450)

Target Description

Doks are a family of adaptor proteins that include six Dok proteins (Dok1 to Dok6), which have an N-terminal pleckstrin homology domain, a central phosphotyrosine binding domain, and a C-terminal region containing multiple tyrosine residues. When phosphorylated, these tyrosines can serve as docking sites for SH2 domain-containing proteins. Dok1 (p62dok) has been shown to bind Ras-GAP, Nck, and Csk. Several tyrosine phosphorylation sites have been identified for Dok1. One site, Tyr-362 (Tyr-361 mouse), is phosphorylated by c-Abl, is required for Nck binding, and may be critical for filopodia formation during fibroblast spreading on fibronectin. Alternatively, Dok1 activity is also regulated by serine phosphorylation. IκB Kinase β phosphorylates several serine sites including Ser-450 in vitro, and TNFα, IL-1, and radiation treatment lead to phosphorylation of Ser-443, Ser-446, and Ser-450 in vivo. Phosphorylation of these serine sites may be required for Dok-mediated inhibition of MAPK signaling and stimulation of cell motility.

Molecular Weight

Antigen

Phospho-Dok1 (Ser-450) synthetic peptide (coupled to KLH) corresponds to amino acids surrounding serine 450 in human Dok1. This sequence is conserved in Dok1 from rat (Ser-449) and mouse (Ser-451). The site is not conserved in other Dok family members.

Species Reactivity

Human, Mouse, Rat

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Conjugate

Unconjugated

Specificity

This antibody was cross-adsorbed to an unphosphorylated Dok1 (Ser-450) peptide before affinity purification using phospho-Dok1 (Ser-450) peptide. The purified antibody detects a band at 62 kDa* corresponding to Dok1 in western blots of human Jurkat cells, but does not detect this band after lambda phosphatase treatment. Similar to Dok1 (Tyr-362) antibody, this antibody also detects an 80 kDa band that has not been identified.
