Crystal structure of human Spindlin1 in complex with a histone H4K20(me3) peptide
Structural highlights
FunctionSPIN1_HUMAN May play a role in cell-cycle regulation during the transition from gamete to embryo (By similarity). Publication Abstract from PubMedUsing methods combining cross-linking, pull-down assays, and stable isotope labeling by amino acids in cell culture with mass spectrometry, we identified that the Tudor domain-containing protein Spindlin-1 recognizes trimethylation of histone H4 lysine 20 (H4K20me3). The binding affinity of Spindlin-1 to H4K20me3 is weaker than that to H3K4me3, indicating H4K20me3 as a secondary substrate for Spindlin-1. Structural studies of Spindlin-1 in complex with the H4K20me3 peptide indicate that Spindlin-1 attains a distinct binding mode for H4K20me3 recognition. Further biochemical analysis identified that Spindlin-1 also binds methylated R23 of H4, providing new clues for the function of Spindlin-1. Spindlin-1 recognizes methylations of K20 and R23 of histone H4 tail.,Wang C, Zhan L, Wu M, Ma R, Yao J, Xiong Y, Pan Y, Guan S, Zhang X, Zang J FEBS Lett. 2018 Dec;592(24):4098-4110. doi: 10.1002/1873-3468.13281.
