Tag :

Expression System:

Sequence :

Specificity :Recognizes the PAK1 protein phosphorylated at threonine 212

Cited Applications :WB, IHC

Cross Reactivity :Human, Mouse and Rat

Host / Isotype / Clone# :Rabbit, IgG

Immunogen :Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr212

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 extracts from HEK293 cells using PAK1 antibody (lanes 1 and 2) and anti-phospho-PAK1 (Thr212) antibody (lanes 3 and 4).

Sample Data :Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue using anti-phospho-PAK1 (Thr212) antibody.

Scientific Background :In mammals, there are several isoforms of p21-activated protein kinases or PAKs. PAKs 1, 2 and 3 are members of the serine/threonine p21-activating kinases that serve as targets for the small GTP binding proteins Cdc42 and RAC1. They have been implicated in wide range of biological activities, which include cytoskeletal reorganization, cellular proliferation and nuclear signaling. CDC42 and RAC1 induce autophosphorylation of PAK2, which stimulates sustained phosphorylation of other substrates (2). ERK phosphorylates and binds to Thr212 of PAK1. Thus, PAK1 may serve as a scaffold for a protein complex, which includes RAF, MEK and ERK (3).
