Enriched in intestine based on RNA-seq studies. Is predicted to encode a protein with the following domains: Immunoglobulin I-set domain; Immunoglobulin-like domain superfamily; EGF-like domain; Laminin EGF domain; Laminin-type EGF domain; Immunoglobulin subtype 2; Concanavalin A-like lectin/glucanase domain superfamily; Low-density lipoprotein (LDL) receptor class A repeat; Immunoglobulin I-set; Immunoglobulin-like domain; Laminin IV; Immunoglobulin domain; LDL receptor-like superfamily; Laminin G domain; Laminin B (Domain IV); Immunoglobulin-like fold; Growth factor receptor cysteine-rich domain superfamily; Low-density lipoprotein receptor domain class A; and Immunoglobulin subtype. Is an ortholog of C. elegans tag-297 and unc-52. In C. elegans, unc-52 is involved in several processes, including hemidesmosome assembly; muscle cell cellular homeostasis; and muscle structure development.
