A user-friendly, inexpensive EXCEL-based program to find potential phosphor
ylation sites in proteins is presented. The input of the program is a prote
in sequence in single letter code. The program searches for 93 different pr
otein kinase recognition sites from 30 different protein kinases. The outpu
t is a list of these sites and their position in the sequence. The program
can easily be updated in case new recognition sites are described. With a f
ew adaptations, the tool can also be used to find other patterns in a prote
in sequence. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
