• PubMed Abstract: 
  

  The hematopoietic cellular kinase (Hck) is a member of the Src family of non-receptor protein-tyrosine kinases and participates in signal transduction events regulating the growth, differentiation and function of phagocytes. The secondary structure of the SH2 domain for Hck was determined for a 13C/15N-enriched sample using multi-dimensional NMR spectroscopy. The secondary structure for the domain was determined from chemical shift indices [1H alpha, 13C alpha and 13C'], sequential NOEs [d(alphaN)(i, i+1) and d(NN)(i, i+1)], and 3J(alphaN) scalar coupling constants. The Hck SH2 domain consists of two alpha-helices and seven beta-strands. Complementary strands of beta-sheets were identified from long-range NOEs using a novel 3D, 13C/15N-edited HMQC-NOESY-(HCACO)NH experiment that correlated 1H alpha resonances between beta-strands. The secondary structure for Hck SH2 is similar to that predicted from the sequence alignment of the Src-family protein tyrosine kinases.
