Q9SHQ9 · SPER4_ARATH

Function

function

Adapter-like transcriptional repressor recruiting TPL/TPR coepressors to inhibit TCP transcription factors (By similarity).
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.
