2. Human erythropoietin (EPO) in different protein sequence databases

Find, if it exists, one entry corresponding to human erythropoietin protein sequence in the following protein sequence databases

NCBInr http://www.ncbi.nlm.nih.gov/
RefSeq http://www.ncbi.nlm.nih.gov/RefSeq/
UniProtKB http://www.uniprot.org/find sequence(s) in UniProtKB/Swiss-Prot and sequence(s) in UniProtKB/TrEMBL
PIR-PSD http://pir.georgetown.edu/pirwww/dbinfo/pir_psd.shtml
UniParc http://www.uniprot.org/
UniRef50 http://www.uniprot.org/
Ensembl http://www.ensembl.org/Homo_sapiens/searchview
IPI IPI query

Find the UniProtKB/Swiss-Prot entry corresponding to:

RefSeq NP_036231 - GI:584682

Tricks:
You can use the query tool provided by each database.
You can use SRS
You can use the crosslinks (if they exist) to go from one database to another...
You can use the ID/AC mapping tool provided by UniProt

NCBInr: GenPept CAA26095
NCBInr: RefSeq NP_000790
UniProtKB/TrEMBL: none
UniProtKB/Swiss-Prot: P01588
