Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Ajuba Antibody detects endogenous levels of total Ajuba protein.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) derived from the sequence of human Ajuba. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from P19 cells (lane 1) and COS-7 cells transfected with Ajuba (lane 2), using Ajuba Antibody.

Western Blotting

Western Blotting

Western blot analysis of extracts from MEF -/- cells rescued with Flag-Ajuba (lane 1), MEF -/- cells (lane 2), MEF +/+ cells (lane 3) and P19 cells (lane 4), using Ajuba Antibody. (Kindly provided by Dr. Gregory D. Longmore, Washington University, St. Louis, Missouri.)

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of COS cells, using Ajuba antibody (blue) compared to a non-specifc negative control antibody (red).


IF-IC

IF-IC

Flourescent Immunocytochemistry analysis of human (HaCaT) and mouse (P19) cells, using Ajuba Antibody (red) and E-cadherin antibody (green). Merged images show colocalization of Ajuba and E-cadherin (yellow) and cell nuclei are identified by Hoechst staining (blue). (Kindly provided by Dr. Gregory D. Longmore, Washington University, St. Louis, Missouri.)

Background

Ajuba belongs to the Zyxin/Ajuba family, members of which include LIMD1, LPP, Trip6 and Zyxin. Three LIM domains at the carboxy-terminus characterize this family of proteins. Zyxin/Ajuba family members associate with the actin cytoskeleton, are components of both cell-cell junction adhesive complex and integrin-mediated adhesive complex, and shuttle in and out of the nucleus (1). Ajuba is involved in Rac activation during cell migration and activates Aurora A in order to commit to mitosis (2-3). Ajuba and its family members also have an amino-terminal proline-rich pre-LIM region, and Ajuba augments ERK activation in a Ras-dependent manner (4).
