Protein: Filamin-A (FLN-A) (Actin-binding protein 280) (ABP-280) (Alpha-filamin) (Endothelial actin-binding protein) (Filamin-1) (Non-muscle filamin) (Q8BTM8)
Organism: Mus musculus (Mouse)
Function: Actin binding protein that promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. Anchors various transmembrane proteins to the actin cytoskeleton and serves as a scaffold for a wide range of cytoplasmic signaling proteins (By similarity). Interaction with FLNB may allow neuroblast migration from the ventricular zone into the cortical plate. Tethers cell surface-localized furin, modulates its rate of internalization and directs its intracellular trafficking. Involved in ciliogenesis. Plays a role in cell-cell contacts and adherens junctions during the development of blood vessels, heart and brain organs. Plays a role in platelets morphology through interaction with SYK that regulates ITAM- and ITAM-like-containing receptor signaling, resulting in by platelet cytoskeleton organization maintenance. During the axon guidance process, required for growth cone collapse induced by SEMA3A-mediated stimulation of neurons.

Cell projection, growth cone {ECO:0000269|PubMed:25358863}. Cell projection, podosome {ECO:0000269|PubMed:23525008}. Note=Colocalizes with CPMR1 in the central region of DRG neuron growth cone (PubMed:25358863). Following SEMA3A stimulation of DRG neurons, colocalizes with F-actin (PubMed:25358863). Localized to the core of myotube podosomes (PubMed:23525008). {ECO:0000269|PubMed:23525008, ECO:0000269|PubMed:25358863}.
