CRYSTAL 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.
NonStd Res:
Gene:	SDCBP OR MDA9 OR SYCL (Homo sapiens)
Resources:	FirstGlance, OCA, RCSB, PDBsum

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]

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.
