Cysteine-rich domain

The major surface coat component of Toxocara larvae runs as a set of four closely migrating bands with apparent mobility of 120 kDa on SDS-PAGE. One of these was cloned and sequenced, identified as a serine-rich mucin and designated MUC-1 (Gems and Maizels, 1996). We have now established that there are at least five distinct mucin genes in this parasite, which bear general similarity but important distinctions. Thus, MUC-2, MUC-3, MUC-4 and MUC-5 are all threonine-rich rather than serine-rich, and all five differ in the repeat motifs within the mucin domains. All have similar non-mucin, cysteine-rich domains originally termed NC6 (nematode six-cysteine) domains, and since renamed SXC (six-cysteine), as described below. All mucins have a pair of SXC domains at their C-terminus, while MUC-3 and MUC-5 also have paired N-terminal SXC domains. [Pg.245]

The second type of aberrant Fas, designated as the membrane-binding decorative receptor, which has substitutions of amino acid(s) within the EC domain, leading to an alteration of the conformation of Fas-ligand binding site (Bl), especially in cysteine-rich domains, can be anchored in the cell membrane. However, this... [Pg.127]

ErbB receptors exhibit conserved structural similarity and domain topography (Fig. 1). They contain an extracellular ligand-binding region, which consists of two cysteine-rich domains, and is responsible for ligand-induced receptor dimerization. This... [Pg.105]

Fig. 2.1 Multi-domain structural organization of gastrointestinal gel-forming mucins. Schematic drawings (not at scale) of the different domains found in gastrointestinal mucins and their roles. Note that while the cysteine-rich domains (D-, CS-, C-, and CK-domains) have a similar length among mucin alleles, the O-glycosylated regions, except in the case of MUC5B, differ in size, a feature not shown in the drawings...

D-domain, which contains up to 30 cysteines and up to 400 amino acid residues, shows significant sequence identity with the other D-domains, especially the cysteine, glycine, and proline residues. Further analysis of the D-domain sequences has defined a potential domain, known as the trypsin inhibitor-like cysteine-rich domain (TIL) within each D-domain sequence (Lang et al. 2004). The NH2-terminal D-domains are involved in formation of mucin disulfide-linked oligomers/multimers (Perez-Vilar and Hill 1999 Perez-Vilar and Mabolo 2007 see Section 2.3.2). [Pg.25]
