'''Ultrahigh resolution Crystal Structure of syntenin PDZ2'''<br />


==Overview==
==Ultrahigh resolution Crystal Structure of syntenin PDZ2==
The crystal structure of the second PDZ domain of the scaffolding protein, syntenin was solved using data extending to 0.73 A resolution. The, crystallographic model, including the hydrogen atoms and the anisotropic, displacement parameters, was refined to a conventional R-factor of 7.5%, and Rfree of 8.7%, making it the most precise crystallographic model of a, protein molecule to date. The model reveals discrete disorder in several, places in the molecule, and significant plasticity of the peptide bond, with some omega angles deviating by nearly 20 degrees from planarity. Most, hydrogen atoms are easily identifiable in the electron density and weak, hydrogen bonds of the C-H...O type are clearly visible between the, beta-strands. The study sets a new standard for high-resolution protein, crystallography.

Structural highlights

1r6j is a 1 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 0.73Å
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.
