GeneCards Summary for SMAP2 Gene

SMAP2 (Small ArfGAP2) is a Protein Coding gene. Diseases associated with SMAP2 include dentin dysplasia, type i, with microdontia and misshapen teeth. Among its related pathways are Endocytosis and Gastric cancer network 1. An important paralog of this gene is ADAP1.

UniProtKB/Swiss-Prot for SMAP2 Gene

  • GTPase activating protein that acts on ARF1. Can also activate ARF6 (in vitro). May play a role in clathrin-dependent retrograde transport from early endosomes to the trans-Golgi network (By similarity).
