If not noted otherwise, the sequence for all predictions is the HEXA Reference sequence. A protocol for this task can be found here.

HEXA LAMP-1 and ALB contain a signal peptide. HEXA has an assigned peptide between position 1 and 22, LAMP-1 between 1 and 28 and ALB between position 1 and 18.
LAMP-1 is a membrane protein which passes the membrane with one helix. ALB, the main protein of plasma, is a secreted extracellular protein. AQP-4 is a multi-pass membrane protein which forms a waterspecific channel and functions in transport.

The prediction of the displayed results was performed with SignalP version 4.0.
SignalP employs 3 main scores for the prediction of signal peptides, C, S and Y. The S-score stands for the actual signal peptide prediction, with high scores indicating that the corresponding amino acid is part of a signal peptide, and low scores indicating that the amino acid is part of a mature protein. The C-score is the cleavage score, which indicates the best cleavage cite when significantly high. (When a cleavage site position is referred to by a single number, the number indicates the first residue in the mature protein.) Y-max is a derivative of the C-score combined with the S-score calculated to give a better cleavage site prediction than the raw C-score alone.
There are two additional scores reported in the SignalP output, namely the S-mean and the D-score. The S-mean is the average of the S-score, ranging from the N-terminal amino acid to the amino acid assigned with the highest Y-max score. The D-score is implemented as a weighted average of the S-mean and the Y-max scores.
For non-secretory proteins all scores are supposed to be very low.
