Rabbit ASK1 Polyclonal Antibody | anti-ASK1 antibody

RABBIT ANTI HUMAN ASK1 (pSer83)

Cat. Num. AAA221528

• Gene Names: MAP3K5; ASK1; MEKK5; MAPKKK5
• Applications: ELISA, Western Blot
• Synonyms: ASK1; Polyclonal Antibody; RABBIT ANTI HUMAN ASK1 (pSer83); anti-ASK1 antibody

• Host: Rabbit
• Clonality: Polyclonal
• Isotype: IgG
• Specificity: This item detects Apoptosis Signal-regulating Kinase 1 (ASK1) phosphorylated at serine83. ASK1 is a serine/threonine kinase also known as MAP kinase kinase kinase (MAPKKK), and plays an important role in the apoptotic response to various stimuli including oxidative stress, cytokines (e.g. TNF) and endoplasmic reticulum stress. Akt in conjunction to Hsp90 phosphorylates ASK1 at Ser83 to inhibit ASK1 induced apoptosis.
• Form/Format: Purified; Purified IgG - liquid
• Concentration: IgG concentration 2.0mg/ml (varies by lot)
• Sequence Length: 1374

• Applicable Applications for anti-ASK1 antibody: ELISA (EIA), Western Blot (WB)*
• Application Notes: Western Blot: This item detects a band of approximately 155kDa in SW1353 cell lysates.; ELISA: Minimum Dilution: 1/5,000; Maximum Dilution: 1/10,000; Western Blotting: Maximum Dilution: 1/1,000; Application Note: For the detection of phosphoproteins, tyrosine phosphatase inhibitors such as 1mM Sodium Orthovanadate should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background.
• Perservative Stabilisers: 0.01% Sodium Azide (NaN3)
• Immunogen: KLH conjugated peptide corresponding to amino acids 76-87 of human ASK-1 protein.; Buffer Solution
• Antiserum Preparation: Antisera to ASK1 (pSER83) were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG was prepared from whole serum by ion exchange chromatography.
• Target Species: Human
• Preparation and Storage: Store at 4 degree C or at -20 degree C if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.; Shelf Life: 18 months from date of despatch.

NCBI Description

Mitogen-activated protein kinase (MAPK) signaling cascades include MAPK or extracellular signal-regulated kinase (ERK), MAPK kinase (MKK or MEK), and MAPK kinase kinase (MAPKKK or MEKK). MAPKK kinase/MEKK phosphorylates and activates its downstream protein kinase, MAPK kinase/MEK, which in turn activates MAPK. The kinases of these signaling cascades are highly conserved, and homologs exist in yeast, Drosophila, and mammalian cells. MAPKKK5 contains 1,374 amino acids with all 11 kinase subdomains. Northern blot analysis shows that MAPKKK5 transcript is abundantly expressed in human heart and pancreas. The MAPKKK5 protein phosphorylates and activates MKK4 (aliases SERK1, MAPKK4) in vitro, and activates c-Jun N-terminal kinase (JNK)/stress-activated protein kinase (SAPK) during transient expression in COS and 293 cells; MAPKKK5 does not activate MAPK/ERK.

Uniprot Description

ASK1: a MAP kinase kinase kinase of the STE11 family, apoptosis signal-regulating kinase 1 (ASK1) plays essential roles in stress-induced apoptosis. Activated by various stressors, including oxidative stress, endoplasmic reticulum stress, and calcium overload, as well as by receptor-mediated inflammatory signals, such as the tumor necrosis factor (TNF) and lipopolysaccharide (LPS). In turn, ASK1 phosphorylates and activates two different subgroups of MAP kinase kinases, MKK4/SEK1 and MKK3/MKK6, which in turn activate stress-activated protein kinases (JNKs) and p38 subgroups of MAP kinases, respectively. Overexpression activates JNK and p38 and induces apoptosis in several cell types through signals involving the mitochondrial cell death pathway. Embryonic fibroblasts or primary neurons derived from ASK1-/- mice are resistant to stress-induced JNK and p38 activation as well as cell death. Oxidative stress induces the activation of ASK1, which correlate with ASK1 activity and ASK1-dependent apoptosis. Required for the innate immune response, which is essential for host defense against a wide range of pathogens.
