Function
function
Adapter-like transcriptional repressor recruiting TPL/TPR coepressors to inhibit TCP transcription factors (By similarity).
May be involved in leaf development
May be involved in leaf development
Miscellaneous
Knock down expression of SPEAR2/TIE4 and SPEAR4/TIE3 by RNAi in a SPEAR3/TIE1 null mutant produces lines displaying epinastic leaves.
