Integrin beta pat-3; Integrin alpha ina-1/beta pat-3 is a receptor for laminin. Integrin alpha pat-2/beta pat-3 recognizes the sequence R-G-D in its ligands (Probable). Plays a role in cell migration, morphogenesis and probably in cell-cell interactions. During gonad morphogenesis, involved in distal tip cell (DTC)-mediated guidance of gonad elongation, in maintaining their sharp tapering morphology and in their migration. Component of an integrin containing attachment complex, which is required for muscle development and maintenance. Involved in the assembly of dense bodies and M line [...]

Basement membrane proteoglycan; Component of an integrin containing attachment complex, which is required for muscle development and maintenance. Probable structural role in myofilament assembly and/or attachment of the myofilament lattice to the cell membrane. May be an extracellular anchor for integrin receptors in body wall muscles and myoepithelial sheath cells. During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles, probably downstream of the integrin complex formed by pat-2 and pat-3. Involved in ovulation.

Papilin; Involved in pharynx morphogenesis probably by remodeling the basement membrane. [Isoform b]: Plays a role in post embryonic distal cell tip migration. Essential extracellular matrix (ECM) protein required for hypodermal enclosure in the embryo.

Integrin alpha pat-2; Required for muscle development probably through the regulation of the actin-myosin cytoskeleton. Component of an integrin containing attachment complex, which is required for muscle maintenance. During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles, probably through lamins such as epi-1, lam-2 and unc-52. Required for distal tip cell migration and dorsal pathfinding. Required for egg-laying. May play a role in cell motility and cell-cell interactions (By similarity). Plays a role in vu [...]

SPARC; Has a high affinity for collagen. Affects nematode body morphology and mobility. Essential for C.elegans development and muscle function. The cysteine-rich region could have protease inhibitory activity or may provide the framework for a protein binding module. Probable role in skeletal morphogenesis; Belongs to the SPARC family.

Laminin-like protein epi-1; During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles, probably downstream of the integrin complex formed by pat-2 and pat-3.

Integrin alpha ina-1; Plays a role in cell migration, axon fasciculation, and morphogenesis. During gonad morphogenesis, involved in distal tip cells (DTC)-mediated guidance of gonad elongation, in maintaining their sharp tapering morphology and in their migration. Involved in the anterior-posterior positioning of QR neuroblast descendants by regulating the migratory speed of QR.p. Probably by acting as a receptor for apoptotic cells, plays a role in the clearance of apoptotic cells during mid-embryogenesis. Belongs to the integrin alpha chain family.

Fibulin-1; Incorporated into fibronectin-containing matrix fibers. Plays a role in cell adhesion and migration along protein fibers within the extracellular matrix (ECM). Important for certain developmental processes and contributes to the supramolecular organization of ECM architecture, in particular to those of basement membranes. [Isoform c]: Involved in the assembly of the flexible hemicentin-containing tracks found joining the pharynx and body-wall- muscle basement membranes; Belongs to the fibulin family.

Putative cuticle collagen 99; Nematode cuticles are composed largely of collagen-like proteins. The cuticle functions both as an exoskeleton and as a barrier to protect the worm from its environment (By similarity).
