Our objectives are to monitor progress toward the C-HPP challenges of MP50, identifying PE2,3,4 proteins for which protein-level evidence now justifies elevation to PE1, and CP50, assisting all investigators with predictions of functions, in Gene Ontology terms, for the large number of PE1 proteins lacking functional annotation (1254, as of neXtProt 2020-02).    The annual HPP Metrics paper for the JPR Special Issue (Table 2) documents chromosome-by-chromosome the progress on the MP and CP initiatives.
