Comment

The SPIN1 gene encodes the spindlin 1 methyl-lysine reader protein. It recognises dimethylated histone H3 arginine 8 (H3R8me2a) and trimethylated histone H3 lysine 4 (H3K4me3) modifications and acts as a transcriptional coactivator. It has non-reader functions including roles in spindle stability maintenance and chromosome segregation. SPIN1 is overexpressed in several types of malignancies, making it a target for anti-cancer drug development.
