Figure 1. Human Chk1 domain structure, interacting proteins and function of each domain.

Figure 1

SQ, Ser/Gln cluster; CM, conserved motif; NES, nuclear export signal; NLS, nuclear localization signal; h, human; sp, S pombe; x, Xenopus; PIP, PCNA-interacting protein. Location of each domain is based on human Chk1. Lines illustrate regions of Chk1 that interact with other proteins. Phosphorylation sites are indicated.
