Sequence-enriched region proteins finder

Upload a FASTA file or enter sequence manually to analyze pattern distribution. The retrieved conditions will be presented right now, while those that have not been retrieved will take 3-5s. Mutant datasets may take even longer (about 5min).

Example result

Pattern

Pattern (Task Word):

Pattern Syntax:

D-E: Matches D or E at the position.
DE: Matches the exact dipeptide "DE".
.D: Matches any residue followed by D.

Analysis Mode

Fixed Mode (Target mode) – Specify exact (hit, window) pairs

Formula Mode (Scan mode) – Use two reference points to derive dynamic window size

Score Mode (Smith-Waterman) – Use a scoring threshold

Proportion Mode (Rate mode) – Use a proportion threshold for analysis

Formula Mode: Reference Points

Define two data points (Hit Count, Window Size) to calculate scanning window dynamically.

Point 1

Hit Count:

Window Size:

Point 2

Hit Count:

Window Size:

Fixed Mode

Enter comma-separated hit/window pairs: hit1,window1,hit2,window2,...

Fixed Points:

Score Mode

Score Threshold: Sequences with score ≥ threshold will be reported (should not be lower than 10).

Proportion Mode

Proportion Threshold: Sequences with proportion ≥ threshold will be reported (range: 0.0 to 1.0).
