Secondly, another insert of 20 amino acids in the 10th spectrin repeat, termed SH3i+, contains protein kinase A and protein kinase C phosphorylation sites and modulates Ca2+-dependent cleavage of spectrin and protein-protein interaction properties. (wikipedia.org)
HN - 2017 MH - ADAM12 Protein UI - D000072199 MN - D8.811.277.656.675.374.102.125 MN - D9.400.430.500.125 MN - D12.776.395.33.125 MS - A disintegrin and metalloproteinase domain-containing protein that is expressed as two alternatively-spliced forms: a long transmembrane form (ADAM12-L) and a short soluble form (ADAM12-S). It modulates the cleavage of INSULIN-LIKE GROWTH FACTOR BINDING PROTEINS and may also regulate CELL FUSION during MYOGENESIS. (nih.gov)
Modulates1
First, a cardiac-specific, 21 amino acid sequence insert in the 21st spectrin repeat, termed alpha II-cardi+, was identified as an insert that modulates affinity of alpha II-spectrin for binding beta-spectrins and regulates myocyte growth and differentiation. (wikipedia.org)
Tissue1
In cardiac tissue, alpha II-spectrin is found in myocytes at Z-discs, costameres, and the sarcolemma membrane, and in cardiac fibroblasts along the surface of the cytoskeletal network. (wikipedia.org)
Functional2
Functional diversity of alpha II-spectrin is manifest through its four splice variants. (wikipedia.org)
It cleaves the membrane-bound precursor of TUMOR NECROSIS FACTOR-ALPHA between ALANINE 76 and VALINE 77 to its functional form, as well as several other CELL SURFACE PROTEINS to their soluble forms, including AMYLOID BETA-PROTEIN PRECURSOR and PRION PROTEIN. (nih.gov)
