Published Data
Mouse Anti-ACTN4 Recombinant Antibody (4D10) (CBMAB-0020CQ) in IHC
IHC of FFPE tissue on consecutive slides of normal pancreatic tissue (panel A-C) and pNEN (panel D-F), small inserts show the corresponding negative controls. Staining for Actn-4sv (A, D), CgA (B, E), and Syn (C, F). In normal pancreas the islet cells are stained for CgA and Syn but not for Actn-4sv. In contrast in pNEN a strong staining for the three markers is visible. (Magnification x 200) ...View More

Full Name
Actinin Alpha 4
Introduction
Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. Alpha-actinin is highly expressed in the glomerular podocyte, is important in nonmuscle cytoskeletal function, and is upregulated early in the course of some animal models of nephrotic syndrome. Using immunohistochemistry, El-Husseini et al. (2000) showed that rat RNF22 and ACTN4 are expressed in a punctate pattern throughout the cytoplasm and neuritic processes of differentiated PC12 cells. They concluded that the isoform of ACTN4 they identified may act to anchor microfilaments to various cellular structures.

Function
F-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein (Probable). Probably involved in vesicular trafficking via its association with the CART complex. The CART complex is necessary for efficient transferrin receptor recycling but not for EGFR degradation. Involved in tight junction assembly in epithelial cells probably through interaction with MICALL2. Links MICALL2 to the actin cytoskeleton and recruits it to the tight junctions (By similarity). May also function as a transcriptional coactivator, stimulating transcription mediated by the nuclear hormone receptors PPARG and RARA.
Biological Process
Negative regulation of substrate adhesion-dependent cell spreading
Peroxisome proliferator activated receptor signaling pathway
Platelet degranulation
Positive regulation of cell migration
Positive regulation of cellular component movement
Positive regulation of NIK/NF-kappaB signaling
Positive regulation of sodium:proton antiporter activity
Protein transport
Regulation of apoptotic process
Regulation of nucleic acid-templated transcription
Response to hypoxia
Retinoic acid receptor signaling pathway
Tumor necrosis factor-mediated signaling pathway
Vesicle transport along actin filament
Cellular Location
Nucleus; Cytoplasm; Stress fiber; Cell junction. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Nuclear translocation can be induced by the PI3 kinase inhibitor wortmannin or by cytochalasin D. Exclusively localized in the nucleus in a limited number of cell lines (breast cancer cell line MCF-7, oral floor cancer IMC-2, and bladder cancer KU-7).
Involvement in disease
Focal segmental glomerulosclerosis 1 (FSGS1): A renal pathology defined by the presence of segmental sclerosis in glomeruli and resulting in proteinuria, reduced glomerular filtration rate and progressive decline in renal function. Renal insufficiency often progresses to end-stage renal disease, a highly morbid state requiring either dialysis therapy or kidney transplantation.
