KIB4_ARATH / Q9SRV0 F-box protein KIB4; Protein KINK SUPPRESSED IN BZR1-1D 4 from Arabidopsis thaliana (Mouse-ear cress) (see paper)
Aligns to 59:359 / 393 (76.6%), covers 99.2% of PF03478, 172.0 bits

• function: Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Required for brassinosteroid (BR) signal transduction. Mediates ASK7/BIN2/SK21 inactivation both by competing with substrate binding (e.g. BZR1) and by promoting its ubiquitination and subsequent proteasomal degradation.
  disruption phenotype: Abolished brassinosteroid (BR)-induced ASK7/BIN2/SK21 degradation, and BR-insensitivity. Suppression of the constitutive BR-response phenotype in the dominant mutant bzr1-1D, and accumulation of phosphorylated BZR1.

• function: Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins.
  subunit: Part of a SCF (ASK-cullin-F-box) protein ligase complex (By similarity). Interacts with SKP1A/ASK1.

Aligns to 69:342 / 382 (71.7%), covers 99.6% of PF03478, 164.0 bits

• function: Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Required for brassinosteroid (BR) signal transduction. Mediates ASK7/BIN2/SK21 inactivation both by competing with substrate binding (e.g. BZR1) and by promoting its ubiquitination and subsequent proteasomal degradation.
  subunit: Part of a SCF (SKP1-cullin-F-box) protein ligase complex. Binds directly to several GSK3 family proteins such as SKP1A/ASK1, ASK1/SK11, ASK3/SK12, ASK5/SK13, ASK7/BIN2/SK21, ASK9/SK22 and ASK6/SK23. Interacts with ASK7/BIN2/SK21 in a brassinosteroid (BR)- dependent manner.
  disruption phenotype: Abolished brassinosteroid (BR)-induced ASK7/BIN2/SK21 degradation, and severe BR-insensitivity. Suppression of the constitutive BR-response phenotype in the dominant mutant bzr1-1D, and accumulation of phosphorylated BZR1.

UFO_ARATH / Q39090 Protein UNUSUAL FLORAL ORGANS; F-box only protein 1; AtFBX1 from Arabidopsis thaliana (Mouse-ear cress) (see 6 papers)
Aligns to 112:346 / 442 (53.2%), covers 78.8% of PF03478, 37.9 bits

• function: Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). Considered as a meristem identity factor required for normal growth of the young floral meristem. Acts together with LEAFY to positively regulate the B class floral homeotic genes APETALA3 and PISTILLATA. In this way, operates as a region-specific regulator for petal and stamen development. Alternatively, may play a role as a negative regulator of the C class floral homeotic genes. Interacts together with the SKP1- like protein ASK1 to form a ubiquitin E3 ligase complex and could indirectly promote the ubiquitination and degradation of specific proteins controlling the floral primordia development like repressors of B class floral homeotic genes.
  subunit: Part of a putative SCF (ASK/Cullin/F-box) ubiquitin ligase complex. Interacts with SKP1A/ASK1, SKP1B/ASK2 and ASK11.
