Comments

Comment Type Description
Catalytic Activity ATP + sphinganine = ADP + sphinganine 1- phosphate. {ECO:0000269|PubMed:21330371}.
Catalytic Activity ATP + sphingosine = ADP + sphingosine 1- phosphate. {ECO:0000269|PubMed:21330371}.
Cofactor Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
Disruption Phenotype No visible phenotype under normal growth conditions. {ECO:0000269|PubMed:22275366}.
Enzyme Regulation Activated by phosphatidic acid (PA). Binding with PA stimulates the activity by promoting the binding of substrate to the catalytic site.
Function Involved in the production of sphingolipid metabolites. Phosphorylates sphingosine and various l sphingoid long-chain base (LCB) products, such as phytosphingosine (PHS, 4- hydroxysphinganine), 4-hydroxy-8-sphingenine, 4,8-sphingadienine and D-erythro-dihydrosphingosine, but has a very few activity toward D,L-threo- dihydrosphingosine. Is required for abscisic acid (ABA) signaling that mediates stomatal closure, inhibition of seed germination and root elongation. May function upstream of PLDALPHA1 and phosphatidic acid (PA) in an amplification response to ABA that mediates stomatal closure. {ECO:0000269|PubMed:21330371, ECO:0000269|PubMed:22275366}.
Sequence Caution Sequence=CAA18718.1; Type=Erroneous gene model prediction; Note=The predicted gene At4g21540 has been split into 2 genes: At4g21534 and At4g21540.; Evidence={ECO:0000305}; Sequence=CAB81261.1; Type=Erroneous gene model prediction; Note=The predicted gene At4g21540 has been split into 2 genes: At4g21534 and At4g21540.; Evidence={ECO:0000305};
Similarity Contains 1 DAGKc domain. {ECO:0000255|PROSITE- ProRule:PRU00783}.
Subcellular Location Vacuole membrane {ECO:0000305|PubMed:21330371}; Peripheral membrane protein {ECO:0000305|PubMed:21330371}. Note=Associated with the tonoplast.
Tissue Specificity Hihgly expressed in flowers and siliques and at lower levels in roots, leaves and stems. {ECO:0000269|PubMed:21330371}.
