This predictor is based on an improved encoding method to predict mucin-type O-linked glycosylation sites in mammalian proteins.

NOTE: Please run one job a time. Otherwise, it will overload our system! If you have lots of sequences to predict,  contact Yong-Zi CHEN to ask for the source code and install the CKSAAP_OGlySite in your local machine.

Input Sequence:


Please enter the sequence in FASTA format (without the FASTA header) using the single-letter AA code in capitalization. And notice that the maximal length of the query sequence is 3000.

Please provide your email address which is required (where the result will be sent to).
