Evolutionary divergences in complexin function have complicated our understanding of the role these proteins play in inhibiting the spontaneous fusion of vesicles. To further analyze the functions of gE in VZV replication, a full deletion and point mutations were made in the 62-amino-acid (aa) C-terminal domain.
Here, we provide evidence that the C-terminal UBA domains guard ubiquitin receptors from destruction by preventing initiation of degradation at the proteasome. The important functional elements of the spike [the S1 N-terminal domain (S1-NTD), the S1 C-terminal domain (S1-CTD), the fusion peptide (FP), and the heptad repeat (HR-N)] are colored in the same way as in Figure 1c. The cw-EPR spectra of the labels on A221C (at the C-terminal end of helix S6) and A223C (at the beginning of the cytoplasmic domain) were compared (Fig. 5. 3. Examples On the C terminus of CHIP, there is a U-box domain that interacts with the UBCH5 family of E2 ubiquitin-conjugating enzymes. The C-terminal domain is responsible for the attachment of the protein to the attachment of the protein to the cell wall. But how the CTD functions in these reactions, especially splicing, is CENP-C is a fundamental component of functional centromeres. Here, we show that this domain forms a coiled coil that determines not only the stability but also the selectivity of the multimerization. As a -sandwich domain in multidomain protease, the C-terminal domain plays an important role in proteolysis including regulation of the secretory process, anchoring and swelling the substrate molecule, presenting as an inhibitor for the preprotease and adapting the protein structural flexibility and stability.

C-terminal modifications. The C-terminus of proteins can be modified posttranslationally, most commonly by the addition of a lipid anchor to the C-terminus that allows the protein to be inserted into a membrane without having a transmembrane domain. The unique diversity of this domain superfamily allows BRCT modules to interact forming homo/hetero BRCT multimers, BRCT-non-BRCT interactions, and interactions with DNA strand breaks. The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH).

The non-BRCT N-terminal region of XRCC1 also mediates direct interactions with DNA polymerase [13]. Structurally, PABP is composed of two parts, an N-terminal portion that contains four RNA recognition motifs (RRM) and a C-terminal portion which contains a conserved poly (A)-binding protein C-terminal domain (PABC; CTC or PABP) sequence of 75 residues.

Summary Other designations. Structure of the H1 C-terminal domain and function in chromatin condensation Linker histones are multifunctional proteins that are involved in a myriad of processes ranging from stabilizing the folding and condensation of chromatin to playing a direct role in regulating gene expression. The C-terminal domain of some proteins has specialized functions. In humans, the CTD of RNA polymerase II typically consists of up to 52 repeats of the sequence Tyr-Ser-Pro-Thr-Ser-Pro-Ser. This allows other proteins to bind to the C-terminal domain of RNA polymerase in order to activate polymerase activity. Therefore, CHIP is equipped with a TPR domain at its amino terminus. Despite extensive studies of the well-folding domains responsible for PARN catalysis, the structure and function of the C-terminal domain (CTD) remains elusive. E3BP has a domain structure similar to that of E2h and is composed of one lipoyl domain, the E3-binding domain, and a catalytically incompetent C-terminal domain (Fig. Analysis of chemical shift changes on peptide binding allowed us to map the peptide binding site on PABC and determine the orientation of the peptide in the binding site.
