RT "Mutations in masquerade, a novel serine-protease-like molecule, affect
RT axonal guidance and taste behavior in Drosophila.";

CC -!- FUNCTION: In embryogenesis, has a role in somatic muscle attachment and
CC in the development of axonal pathways probably by stabilizing cell-
CC matrix adhesion and/or by acting as a competitive antagonist of serine
CC proteases. {ECO:0000269|PubMed:7851790, ECO:0000269|PubMed:8817456}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:7851790}. Cell
CC projection, axon {ECO:0000269|PubMed:7851790,
CC ECO:0000269|PubMed:8817456}. Note=Localizes to vesicle-like structures
CC in epidermal cells. {ECO:0000305|PubMed:7851790,
CC ECO:0000305|PubMed:8817456}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=B {ECO:0000312|FlyBase:FBgn0011653};
CC IsoId=Q9VZH2-1; Sequence=Displayed;
CC Name=C {ECO:0000312|FlyBase:FBgn0011653};
CC IsoId=Q9VZH2-2; Sequence=VSP_059330;
CC -!- DEVELOPMENTAL STAGE: In embryos, from stage 14 till stage 17, expressed
CC in epidermal cells, tracheal system and denticle belts (at protein
CC level) (PubMed:7851790). In larva and in early pupa, expressed in brain
CC cells along the ventral midline, in cell bodies in the cellular cortex
CC of the ventral nerve cord, in cells contributing to the perineum around
CC the cerebral hemispheres and in axons of the longitudinal connectives
CC of the central nervous system (CNS); at low level, expressed throughout
CC the antennal disk (at protein level) (PubMed:7851790, PubMed:8817456).
CC In pupae, expressed in pupal appendages and body epidermis, in the
CC proboscis and pseudotrachea (at protein level) (PubMed:8817456).
CC Expressed in embryos; from stage 11 until the end of stage 13 expressed
CC in small cells along the midline of the central nervous system; at
CC state 12, expressed in the epidermis; from stage 13 onwards, expressed
CC in the epidermal cells in particular in the anterior border of each
CC segment; from stage 14-17, detected in the cells of the tracheal system
CC (PubMed:7851790). Detected in larva and pupa, but not in adult flies
CC (PubMed:7851790, PubMed:8817456). {ECO:0000269|PubMed:7851790,
CC ECO:0000269|PubMed:8817456}.
CC -!- DOMAIN: The CLIP domain consists of 37-55 residues which are 'knitted'
CC together usually by 3 conserved disulfide bonds forming a clip-like
CC compact structure. {ECO:0000305}.
CC -!- PTM: Proteolytically cleaved and thereafter secreted.
CC {ECO:0000269|PubMed:7851790}.
CC -!- DISRUPTION PHENOTYPE: Embryonic lethal as a result of neuronal defects
CC in the central nervous system (CNS) and peripheral nervous system (PNS)
CC from stage 15, and defective muscle attachment from stage 16
CC (PubMed:7851790, PubMed:8817456). Defects in the CNS include stalling
CC of the growth cones of pioneer axons of anterior and posterior corner
CC cells (aCC and pCC) leading to abnormalities in the horizontal
CC commissures and discontinuities in the longitudinal connectives
CC respectively (PubMed:8817456). Defects in the PNS include defects in
CC the location of the sense organs and in their projections in the
CC sensory nerves, including missing neurons and more often defects in the
CC axonal paths with erroneous connections with the ventral ganglia
CC (PubMed:8817456). Defects in muscle attachment include the appearance
CC of myospheroid-like bodies and the collapse of lateral transverse
CC muscles 1-3 (PubMed:7851790). {ECO:0000269|PubMed:7851790,
CC ECO:0000269|PubMed:8817456}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. CLIP subfamily.
CC {ECO:0000305}.
CC -!- CAUTION: Lacks the conserved Ser residue within the catalytic triad
CC which is replaced by a Gly residue, probably resulting in a loss of
CC proteolytic activity. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAK93468.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
