Alignment and sequence features

Loading data

Wheel: zoom in/out; drag: scroll left/right. Sequences and features are drawn in three lines. Bottom line: topology (red bar: cytoplasmic region; yellow bar: transmembrane region; transmembrane re-entrant loop; blue bar: extracellular region; black bar: signal peptide). Middle line: amino acid sequence (grey bar or one letter code). Top line: post translational modifications (Y: N-glycosylation site; Y: O-glycosylation site;P: phosphorylation site), intrinsically disordered regions (light green bar: IDR) and short linear motifs (light steel blue bar: ELM region).
