Activity summary

Sarcomeric Alpha Actinin often referred to as alpha-actinin or A-actinin is a protein that functions mechanically as a cross-linker of actin filaments in the sarcomere. It plays a critical role in organizing the actin cytoskeleton providing structural integrity and facilitating muscle contraction. The protein typically has a molecular mass of approximately 100 kDa. It is expressed in a variety of tissues including skeletal and cardiac muscle where it establishes the architecture of the Z-disc by anchoring actin filaments.

Biological function summary

Sarcomeric alpha actinin associates with multiple proteins to form a complex that coordinates muscle function. It not only serves as a structural component but also participates in signaling processes influencing muscle repair and growth. Alpha actinin connects to other cytoskeletal proteins and adaptors coordinating with integrin pathways to transmit external mechanical signals into cellular responses. The ability of alpha actinin to interact with a range of proteins like filamin and spectrin enhances its role in maintaining cellular architecture.

Pathways

Alpha actinin is critical in both the integrin and dystrophin-glycoprotein complex pathways facilitating signal transduction and maintaining muscle stability. Its interaction with actin filaments is important for pathways involving cell adhesion and motility. Within these pathways actin-related proteins such as ACTN2 and titin partner with alpha actinin to sustain cellular structure and function during dynamic processes including muscle contraction and relaxation.

Associated diseases and disorders

Mutations or defects in alpha actinin have implications in muscular dystrophy and cardiomyopathy. These conditions often involve disruptions in the muscle's structural framework and mechanical signaling where alpha actinin's interaction with dystrophin becomes significant. Additionally such disorders may showcase altered connectivity between alpha actinin and spectrin further affecting muscle integrity and function in pathological conditions.

    α-actinin-2 localizes to post-synaptic sites in dendritic spines on hippocampal neurons.A) An anti-α-actinin antibody (ab68167) recognizes α-actinin-2 and not α-actinin-1 or α-actinin-4. CHO-K1 cells were transfected with human α-actinin-1-GFP, α-actinin-2-GFP, or α-actinin-4-GFP. Cells were lysed and immunoblotted for α-actinin-2 and GFP. B) α-Actinin-2 is enriched in hippocampal neurons but not in glia cells or COS-7 cells, which lacks α-actinin-2. Cells were lysed and immunoblotted for α-actinin-2. Actin is the loading control. C) α-Actinin-2 localizes to dendritic spines. Hippocampal neurons were transfected at DIV 17 with GFP (green), and fixed, and immunostained for endogenous α-actinin-2 (magenta) at DIV 21. D) α-Actinin-2 co-localizes with post-synaptic markers, but not with a pre-synaptic marker. Hippocampal neurons were fixed at DIV 16 or 21 and immunostained for endogenous α-actinin-2 (green) and either endogenous synaptophysin, PSD-95, or the NR1 subunit of the NMDA receptor (magenta). E–G) The siRNA is specific for α-actinin-2. Hippocampal neurons were co-transfected at DIV 17 with GFP and either a control empty vector (pSUPER), or a vector containing siRNA against α-actinin-2 (pSUPER-α-actinin-2), or the α-actinin-2 siRNA-containing vector plus a α-actinin-2 vector conferring resistance to RNAi (pSUPER-α-actinin-2+ α-actinin-2-SS). The cells were fixed at DIV 21 and immunostained for endogenous α-actinin-2. Arrows point to the neurons co-expressing GFP and its immunostaining for α-actinin-2. For each condition (55 control cells and 46 α-actinin-2 knockdown cells), the integrated density of the cell body and dendrites were measured from the transfected neuron and adjacent untransfected neuron of the same image and the percent change was plotted, F. Error bars represent SEM. p-values were derived using the paired t-test. G) CHO-K1 cells were co-transfected with GFP, pSUPER or pSUPER-α-actinin-2, plus either α-actinin-2-Flag or α-actinin-2-SS-Flag. Transfection efficiency was close to 100% as >95% of the cells in each condition exhibited GFP fluorescence (data not shown). Cells were lysed 72 hours after transfection and immunoblotted for α-actinin-2 and α-actinin-4. Tubulin is the loading control.
