In Section 21.10 we briefly discussed the Human Proteome Map (HPM). An interactive Web site for the HPM is available at http://www.humanproteomemap.org. Visit this site, and then answer the questions in parts (a) and (b) and complete part (c). Use the 'Query' tab and select the 'Gene family' dropdown menu to do a search on the distribution of proteins encoded by a pathway of interest to you. Search in fetal tissues, adult tissues, or both.
