CC -!- FUNCTION: Cell surface proteoglycan that bears heparan sulfate.
CC Required for axonal and myotube guidance, is a necessary component of
CC slit/robo signaling and is required in the slit target cells.
CC {ECO:0000269|PubMed:14761655, ECO:0000269|PubMed:8159748}.
CC -!- SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=A;
CC IsoId=P49415-1; Sequence=Displayed;
CC Name=B; Synonyms=C;
CC IsoId=P49415-2; Sequence=VSP_011792;
CC -!- TISSUE SPECIFICITY: In 13-16 hours embryos, expressed in lymph glands,
CC peripheral and central nervous system and basal surfaces of gut
CC epithelia. Sdc and robo are coexpressed in domains adjacent to slit; in
CC tracheal pits and midline glia cells. {ECO:0000269|PubMed:14761655,
CC ECO:0000269|PubMed:8159748}.
CC -!- DISRUPTION PHENOTYPE: Flies exhibit aberrant midline guidance of axons
CC and establishment of muscle pattern. {ECO:0000269|PubMed:14761655}.
CC -!- SIMILARITY: Belongs to the syndecan proteoglycan family. {ECO:0000305}.
