Falcon deep research for Arabidopsis TTG1

TTG1 encodes a WD40-repeat scaffold protein that functions primarily as the WD40 subunit of MBW transcriptional activator complexes.
TTG1-dependent MBW complexes regulate epidermal cell fate, trichome initiation, root hair patterning, anthocyanin accumulation, proanthocyanidin accumulation, and seed coat mucilage.

UniProt record for Arabidopsis TTG1

UniProt identifies TTG1/Q9XGN1 as a WD-repeat protein that promotes trichome formation with GL1 and GL3, activates GL2 transcription, and contributes to root hair, seed mucilage, and anthocyanin pathways.

PANTHER PTHR19919 family entries for Arabidopsis TTG1

PTHR19919 places TTG1 in a broad WD-repeat-containing protein family; this supports a scaffold/interaction role but is too broad to transfer TTG1-specific MBW pathway annotations without Arabidopsis evidence.
