The molecular weight of this protein is predicted 93 KD and was named p93, which contains three kinds of protein domains: seven ankyrin repeats (ANK) in N-terminal followed by a protein kinase (PK) domain and a C-teiminal Serine-rich (Ser-rich) domain.

• 结构域组成分析表明p93含三种结构域：N端为7个锚蛋白重复(ankyrin repeats，ANK)结构域，中间为一蛋白激酶(protein kinase，PK)结构域，C末端为富含丝氨酸(Ser-rich)结构域；
