bs-70002R

DATASHEET

Host: Rabbit

Target Protein: 5-Lipoxygenase (Ser523)

Specificity: Specific for endogenous levels of the ~80 kD 5-LO phosphorylated at Ser523 in Western blots. Immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-phosphatase, 1200 units for 30 min).

Modification Site: Ser523

Clonality: Polyclonal

Isotype: IgG

Entrez Gene: 240

Swiss Prot: P09917

Source: Synthetic phosphopeptide corresponding to amino acid residues surrounding Ser523 of human 5-lipoxygenase (5-LO), conjugated to keyhole limpet hemocyanin (KLH).

Purification: Antigen Affinity purification from Pooled whole antiserum

Storage Buffer: 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

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.

Background:

The enzyme 5-lipoxygenase (5-LO) plays a key role in regulating the production of leukotrienes (LTs) (Funk, 2001). Overproduction of LTs contributes to several diseases, most notably chronic inflammatory diseases, including asthma (Drazen et al., 1994), fibrosis (Wilborn et al., 1996) and atherosclerosis (Dwyer et al., 2004). Recent work has demonstrated that the activity of 5-LO is regulated by PKA phosphorylation of serine-523 in 5-LO (Luo et al., 2004). Under normal conditions, this phosphorylation may be important in limiting inflammation. Abnormal signaling through cAMP and PKA, then, could contribute to a variety of diseases, including those characterized by chronic inflammation. The phospho-specific antibody to Ser523 on 5-LO is thus likely to provide a valuable tool for studies of the role of 5-LO regulation in diseases such as asthma, fibrosis and atherosclerosis.
