Encodes a 56-amino acid polypeptide with low but significant similarity to human small subunit of serine palmitoyltransferase that localizes to the ER and physically interacts with and greatly stimulates the activity of LCB1/LCB2 heterodimer ser palmitoyltransferase complex. Mutants have low pollen viability.
At2g30942 and At1g06515 are serine palmitoyltransferase-interacting proteins, which stimulate sphingolipid synthesis and are essential, and affect mycotoxin sensitivity.
