Summaries for STAP2 Gene

Entrez Gene Summary for STAP2 Gene

  • This gene encodes the substrate of breast tumor kinase, an Src-type non-receptor tyrosine kinase. The encoded protein possesses domains and several tyrosine phosphorylation sites characteristic of adaptor proteins that mediate the interactions linking proteins involved in signal transduction pathways. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

GeneCards Summary for STAP2 Gene

STAP2 (Signal Transducing Adaptor Family Member 2) is a Protein Coding gene. GO annotations related to this gene include phospholipid binding. An important paralog of this gene is STAP1.
