SIVmac239 Nef in complex with TCR zeta ITAM 1 polypeptide (A63-R80)

Structural highlights

3ik5 is a 4 chain structure with sequence from Siv - cpz. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	nef (SIV - cpz)

Disease

[CD3Z_HUMAN] Defects in CD247 are the cause of immunodeficiency due to defect in CD3-zeta (CD3ZID) [MIM:610163]. An immunological deficiency characterized by T-cells impaired immune response to alloantigens, tetanus toxoid and mitogens.^[1]

Function

[CD3Z_HUMAN] Probable role in assembly and expression of the TCR complex as well as signal transduction upon antigen triggering.

Publication Abstract from PubMed

HIV/SIV Nef mediates many cellular processes through interactions with various cytoplasmic and membrane-associated host proteins, including the signalling zeta subunit of the T-cell receptor (TCRzeta). Here, the crystallization strategy, methods and refinement procedures used to solve the structures of the core domain of the SIVmac239 isolate of Nef (Nef(core)) in complex with two different TCRzeta fragments are described. The structure of SIVmac239 Nef(core) bound to the longer TCRzeta polypeptide (Leu51-Asp93) was determined to 3.7 A resolution (R(work) = 28.7%) in the tetragonal space group P4(3)2(1)2. The structure of SIVmac239 Nef(core) in complex with the shorter TCRzeta polypeptide (Ala63-Arg80) was determined to 2.05 A resolution (R(work) = 17.0%), but only after the detection of nearly perfect pseudo-merohedral crystal twinning and proper assignment of the orthorhombic space group P2(1)2(1)2(1). The reduction in crystal space-group symmetry induced by the truncated TCRzeta polypeptide appears to be caused by the rearrangement of crystal-contact hydrogen-bonding networks and the substitution of crystallographic symmetry operations by similar noncrystallographic symmetry (NCS) operations. The combination of NCS rotations that were nearly parallel to the twin operation (k, h, -l) and a and b unit-cell parameters that were nearly identical predisposed the P2(1)2(1)2(1) crystal form to pseudo-merohedral twinning.
