Acts as positive regulator of drought and salt tolerance. Acts as positive regulator of cell viability. Interacts with FLO6/SIP4 (PubMed:19339499). Interacts with DIS1 (PubMed:22067990). Widely expressed. Induced by drought, cold and salt stresses. Induced by wounding and treatment with abscisic acid (ABA), jasmonate (JA), salicylic acid (SA) and ethylene. Plants silencing SKIPA exhibit growth arrest and reduced cell viability. Plants overexpressing SKIPA exhibit drought resistance and significantly improved growth performance in medium containing stress agents (abscisic acid, salt, or mannitol). Belongs to the SNW family.
