Synthetic peptide corresponding to Human Ankyrin erythroid (C terminal). The immunogen is a 14aa peptide within this sequence: RRQIDLSSAD AAQEHEEVEL RGSGLQPDLI EGRKGAQIVK RASLKRGKQ, corresponding to C terminal amino acids of Human Ankyrin erythroid Sequence:
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1.25 µg/ml. Detects a band of approximately 21 kDa (predicted molecular weight: 17 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use a concentration of 4 - 8 µg/ml.
功能Attaches integral membrane proteins to cytoskeletal elements; binds to the erythrocyte membrane protein band 4.2, to Na-K ATPase, to the lymphocyte membrane protein GP85, and to the cytoskeletal proteins fodrin, tubulin, vimentin and desmin. Erythrocyte ankyrins also link spectrin (beta chain) to the cytoplasmic domain of the erythrocytes anion exchange protein; they retain most or all of these binding functions. Isoform Mu17 together with obscurin in skeletal muscle may provide a molecular link between the sarcoplasmic reticulum and myofibrils.
组织特异性Isoform Mu17, isoform Mu18, isoform Mu19 and isoform Mu20 are expressed in skeletal muscle. Isoform Br21 is expressed in brain.
疾病相关Defects in ANK1 are a cause of spherocytosis type 1 (SPH1) [MIM:182900]; also called hereditary spherocytosis type 1 (HS1). Spherocytosis is a hematologic disorder leading to chronic hemolytic anemia and characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. Inheritance can be autosomal dominant or recessive.
结构域The 55 kDa regulatory domain is involved in regulating binding of SPTB/spectrin (beta chain) and SLC4A1/erythrocyte membrane protein band 3. The ANK repeat region forms a spiral around a large central cavity and is involved in binding of ion transporters.
翻译后修饰Regulated by phosphorylation. Palmitoylated.
细胞定位Cytoplasm > cytoskeleton. Probably the other erythrocyte (Er) isoforms, are located near the surface of erythrocytic plasma membrane; Sarcoplasmic reticulum and Membrane. Cytoplasm > myofibril > sarcomere > M line. Colocalizes with OBSCN isoform 3/obscurin at the M line in differentiated skeletal muscle cells.
