Abstract
We have characterized the phosphorylation of “abp38” before and after the differ entiation of mouse myeloid leukemic cells (M1 cells). The abp38 of both undiffer entiated and differentiated M1 cells contained phosphoserine and phosphotyrosine. The extent of phosphorylation of abp38 decreased to about 30% of the value, of undifferentiated cells during cell differentiation; phosphoserine and phosphotyrosine decreased to 41 and 11% of the values before differentiation, respectively.Keywords
