Encodes a member of an eight-gene family (SMAX1 and SMAX1-like) that has weak similarity to AtHSP101, a ClpB chaperonin required for thermotolerance. The mRNA is cell-to-cell mobile.
TAIR Short Description
Double Clp-N motif-containing P-loop nucleoside triphosphate hydrolases superfamily protein
Probable component of a transcriptional corepressor complex involved in branching control. Regulates cotyledon expansion and lateral root growth, but not germination or hypocotyl elongation. Promotes auxin transport and PIN1 accumulation in the stem and represses BRC1/TCP18 expression in axillary buds (PubMed:26546446, PubMed:26546447).
Expressed in axillary branches and roots. Detected in seedlings and leaves (PubMed:23893171). Expressed in the primary rosette buds and expanding leaves of adult rosettes, the vasculature of the hypocotyls, cotyledons, and mature roots, and in the midvein and petioles of young leaves (PubMed:26546447).
