KARYOPHERIN ALPHA (YEAST) + SV40 T ANTIGEN NLS

Structural highlights

1bk6 is a 6 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 2.8Å
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

IMA1_YEAST Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. Promotes docking of import substrates to the nuclear envelope. Seems to act as a cytosolic receptor for both simple and bipartite NLS motifs (By similarity).^[1] ^[2] ^[3]

Evolutionary Conservation

Checkto colour the structure by Evolutionary Conservation, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
