General description

Actopaxin is a member of actin binding proteins that include beta-parvin/affixin and gamma-parvin. Actopaxin is known to associate with F-actin and paxillin LD motifs LD1 and LD4. This protein also directly binds to serine/threonine integrin-linked kinase (ILK). Studies have reported that actopaxin may be involved in integrin-dependent remodeling of the actin cytoskeleton during cell adhesion, motility and division.
Rabbit anti-actopaxin recognizes actopaxin (42 kDa). Staining of actopaxin in immunoblotting is specifically inhibited with actopaxin immunizing peptide (mouse, amino acids 35-53).

Immunogen

synthetic peptide corresponding to the N-terminal region of mouse actopaxin (amino acids 35-53). The sequence is identical in human actopaxin and has considerable homology (~70%) with β-parvin/affixin, but no homology with γ-parvin.

Application

Actopaxin was detected in HEK 293 cell lysates at 42 kDa by western blot using rabbit anti-actopaxin antibody at a 1:1000 dilution. In these cells, actopaxin associated with an ILK complex.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Immunofluorescence (1 paper)
Rabbit anti-actopaxin can also be used for protein microaarays.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

Focal adhesions (FAs) are essential structures for cell adhesion, migration, and morphogenesis. Integrin-linked kinase (ILK), which is capable of interacting with the cytoplasmic domain of beta1 integrin, seems to be a key component of FAs, but its exact role in

Kidney anion exchanger 1 (kAE1) mediates chloride/bicarbonate exchange at the basolateral membrane of kidney alpha-intercalated cells, thereby facilitating bicarbonate reabsorption into the blood. Human kAE1 lacks the N-terminal 65 residues of the erythroid form (AE1, band 3), which are essential

We have identified and cloned a novel 42-kDa protein termed alpha-parvin, which has a single alpha-actinin-like actin-binding domain. Unlike other members of the alpha-actinin superfamily, which are large multidomain proteins, alpha-parvin lacks a rod domain or any other C-terminal structural

Paxillin is a focal adhesion adapter protein involved in integrin signaling. We have recently reported that the paxillin LD1 motif acts as a binding interface for both the actin-binding protein actopaxin and the serine/threonine integrin-linked kinase (ILK). In this report

Protein-protein interactions play an essential role in the regulation of vital biological functions. Through a network of interactions, integrin-linked kinase (ILK) functions downstream of integrin receptors to control cell spreading, migration, growth, survival, and cell cycle progression.
