Summary: Enables several functions, including GTP binding activity; identical protein binding activity; and phospholipase binding activity. Involved in several processes, including isopeptide cross-linking via N6-(L-isoglutamyl)-L-lysine; positive regulation of canonical NF-kappaB signal transduction; and positive regulation of smooth muscle cell proliferation. Acts upstream of or within phospholipase C-activating G protein-coupled receptor signaling pathway. Located in cytosol and nucleus. Orthologous to human TGM2 (transglutaminase 2).

Cultured Xbp1-deficient vascular smooth muscle cells (VSMCs) demonstrated decreased levels of TG2 protein, in association with increased TG2 polyubiquitination. Moreover, IRE1alpha, and TG2-specific transamidation cross-links were increased in carotid artery neointima in Xbp1fl/fl SM22alpha-CRE+ mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
