Protein: PALLD_HUMAN

Palladin

FUNCTION: Cytoskeletal protein required for organization of normal actin cytoskeleton. Roles in establishing cell morphology, motility, cell adhesion and cell-extracellular matrix interactions in a variety of cell types. May function as a scaffolding molecule with the potential to influence both actin polymerization and the assembly of existing actin filaments into higher-order arrays. Binds to proteins that bind to either monomeric or filamentous actin. Localizes at sites where active actin remodeling takes place, such as lamellipodia and membrane ruffles. Different isoforms may have functional differences. Involved in the control of morphological and cytoskeletal changes associated with dendritic cell maturation. Involved in targeting ACTN to specific subcellular foci. more...

SUBUNIT: Interacts with EPS8, LASP1 and VASP (By similarity). Interacts with ACTN, ARGBP2, LPP, PFN1, SPIN90, SRC and EZR.

SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Cell junction, focal adhesion. Cell projection, ruffle. Cell projection, lamellipodium. Cytoplasm, myofibril, sarcomere, Z line. Note=Localizes to stress fibers and Z lines.

ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=7; Name=1; Synonyms=200-kDa; IsoId=Q8WX93-1; Sequence=Displayed; Name=2; IsoId=Q8WX93-2; Sequence=VSP_027929, VSP_027930; Name=3; Synonyms=140-kDa; IsoId=Q8WX93-3; Sequence=VSP_027927; Name=4; Synonyms=90-kDa; IsoId=Q8WX93-4; Sequence=VSP_027926; Name=5; IsoId=Q8WX93-5; Sequence=VSP_027929; Note=No experimental confirmation available; Name=6; IsoId=Q8WX93-6; Sequence=VSP_027928; Note=No experimental confirmation available; Name=7; IsoId=Q8WX93-7; Sequence=VSP_027925;

TISSUE SPECIFICITY: Detected in both muscle and non-muscle tissues. High expression in prostate, ovary, colon, and kidney. Not detected in spleen, skeletal muscle, lung and peripheral blood lymphocytes (at protein level).

INDUCTION: Isoform 3 is expressed de novo. Isoform 4 is up- regulated by TGFB1 during myofibroblast differentiation.

PTM: Phosphorylated predominantly on serines and, to a lesser extent, on tyrosines (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR.

DISEASE: Genetic variations in PALLD are associated with susceptibility to pancreatic cancer type 1 (PNCA1) [MIM:606856]. Expression is increased early in the development of pancreatic cancer: in normal-appearing whole tissue immediately adjacent to cancer, in the pre-cancer, and in both the familial and sporadic forms of the cancer.

DISEASE: Note=Genetic variations in PALLD may be associated with myocardial infarction. MISCELLANEOUS: Protein is overexpressed in FA6, HPAF, IMIMPC2, SUIT2 and PATU2 sporadic pancreatic cancer cell lines.

SIMILARITY: Belongs to the myotilin/palladin family.

SIMILARITY: Contains 5 Ig-like C2-type (immunoglobulin-like) domains. CAUTION: Was wrongly assigned as myoneurin (Ref.2).

SEQUENCE CAUTION: Sequence=AAD34146.1; Type=Erroneous initiation; Note=Translation N-terminally shortened; Sequence=AAO65174.1; Type=Frameshift; Positions=1150, 1154; Sequence=BAA76836.1; Type=Erroneous initiation; Note=Translation N-terminally shortened; Sequence=BAC04796.1; Type=Erroneous initiation; Note=Translation N-terminally extended;
