enetnglyc

 

Function

Reports N-glycosylation sites in human proteins

Description

The NetNglyc server predicts N-Glycosylation sites in human proteins using artificial neural networks that examine the sequence context of Asn-Xaa-Ser/Thr sequons.

# Predictions for N-Glycosylation sites in 1 sequence

########################################################################################

    Warning: This sequence may not contain a signal peptide!!

    Proteins without signal peptides are unlikely to be exposed to
    the N-glycosylation machinery and thus may not be glycosylated
    (in vivo) even though they contain potential motifs.

    SignalP-NN euk predictions are as follows:

  # name                Cmax  pos ?  Ymax  pos ?  Smax  pos ?  Smean ?  D     ? 
  LEUK_RAT              0.112  32 N  0.088  16 N  0.362   8 N  0.119 N  0.104 N

    SignalP output is explained at http://www.cbs.dtu.dk/services/SignalP/output.html
