UniProt functional annotation for Q8LAD7



	UniProt functional annotation for Q8LAD7

UniProt code: Q8LAD7.

Organism: Arabidopsis thaliana (Mouse-ear cress).

Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis.

Function: Involved in an ethylene-independent separation step of floral abscission (PubMed:18660431, PubMed:23963677, PubMed:27058169). Promotes abscission zone (AZ) cells rounding (PubMed:23963677, PubMed:27058169). May act with RLK5 and HSL2 as ligand-receptor pairs (PubMed:18660431). {ECO:0000269|PubMed:18660431, ECO:0000269|PubMed:23963677, ECO:0000269|PubMed:27058169}.

Subunit: Interaction with RLK5. {ECO:0000269|PubMed:27058169}.

Subcellular location: Secreted, extracellular space {ECO:0000269|PubMed:12972671}.

Tissue specificity: Expressed specifically in the floral abscission zone. {ECO:0000269|PubMed:12972671}.

Developmental stage: Expressed only during floral abscission. {ECO:0000269|PubMed:12972671}.

Induction: By wounding. {ECO:0000269|PubMed:16990374}.

Domain: An extended PIP motif (50-69) is sufficient for abscission induction.

Disruption phenotype: Floral organs remain attached to the plant body after the shedding of mature seeds despite a normal floral abscission zone development, including abnormal petal breakstrength (pBS) (PubMed:12972671, PubMed:23963677). Delayed cell-wall loosening during shedding associated with less pronounced and delayed abscission zone (AZ) cells rounding (PubMed:23963677). {ECO:0000269|PubMed:12972671, ECO:0000269|PubMed:23963677}.

Miscellaneous: IDL1 is capable of replacing the activity of IDA while IDL2, IDL3, IDL4 and IDL5 are only partially redundant.

Miscellaneous: IDA is processed in vitro by the same proteolytic activity releasing the CLE peptide from CLV3.
