Instead, nesprin-3 contains a plectin-binding domain which links the NE to the cytoplasmic IF networks.
Therefore, the DSC2 A897fsX900 variant appears to have different characteristics, and any pathogenic potential of this variant should be an adverse action at the desmosomes, most likely by affecting binding properties of the intracellular, cytoplasmic domain, which links DSC2 to PG and PKP2.
Our modeling revealed that the enzymatic core is formed by a twisted, six-stranded β-sheet flanked by six helices (α1-α6) linked through a loop region to the cell wall binding domain which consists of two anti-parallel β-sheets.
Calmodulin dependent protein kinase I (299 320) binding domain, which is a putative CaM-binding region, was obtained from AnaSpec.
These tyrosine autophosphorylation residues serve as docking sites for SH2 (Srchomology 2) and phosphotyrosine-binding domain containing protein, which links the activated, phosphorylated HER receptor with downstream cell proliferation (mitogen-activated protein kinase [MAPK]) and survival (phosphatidyl-inositol-3 kinase [PI3K]) signaling pathways [ 5, 6].
The FtsI domain contains a penicillin-binding protein transpeptidase domain, which putatively cross-links peptidoglycan chains to form a rigid cell wall structure.
Two of the identified positions are located in the switch loop, which links domains 3 and 4 and undergoes a conformational rearrangement upon ribosome binding.
Intracytoplasmatic phosphorylated tyrosine residues of the Her-2/ neu molecule function as high-affinity binding sites for SH2 domain containing proteins, which link the receptor to intracellular signal transduction processes such as the ras-raf-mitogen activated protein kinase (MAPK) and the phosphatidylinositol-3 kinase (PI-3 K) pathways.
Moreover, the endo-β-glucanase and exo-β-glucanase from T. reesei have a conserved tripartite structure with a large catalytic core domain linked by an O-glucosylated peptide to a cellulose-binding domain (CBD), which is required for interaction with crystalline cellulose [ 8, 9].
These custom DNA binding domains were linked to the mSin3A interaction domain (SID) to generate TALE SID chimeric repressors.
