CRYSTAL STRUCTURE OF THE PDZ TANDEM OF HUMAN SYNTENINCRYSTAL STRUCTURE OF THE PDZ TANDEM OF HUMAN SYNTENIN

Structural highlights

1n99 is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.94Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

SDCB1_HUMAN Seems to function as an adapter protein. In adherens junctions may function to couple syndecans to cytoskeletal proteins or signaling components. Seems to couple transcription factor SOX4 to the IL-5 receptor (IL5RA). May also play a role in vesicular trafficking. Seems to be required for the targeting of TGFA to the cell surface in the early secretory pathway.[1] [2] [3]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

Syntenin, a 33 kDa protein, interacts with several cell membrane receptors and with merlin, the product of the causal gene for neurofibromatosis type II. We report a crystal structure of the functional fragment of human syntenin containing two canonical PDZ domains, as well as binding studies for full-length syntenin, the PDZ tandem, and isolated PDZ domains. We show that the functional properties of syntenin are a result of independent interactions with target peptides, and that each domain is able to bind peptides belonging to two different classes: PDZ1 binds peptides from classes I and III, while PDZ2 interacts with classes I and II. The independent binding of merlin by PDZ1 and syndecan-4 by PDZ2 provides direct evidence for the coupling of syndecan-mediated signaling to actin regulation by merlin.
