Short name: SRK-like_kinase

Family relationships

None.

Description

Plant S-receptor kinase-like genes have diverse functions in cell signalling, development, stress responses and host-pathogen defence responses [PMID: 12142267].

This entry contains receptor-like kinases, including S-locus receptor kinase (SRK). SRK is the female determinant of the self-incompatibility (SI) response in Brassica [PMID: 1681543, PMID: 10706292]. Flowering plants apply a self-incompatibility mechanism to prevent inbreeding and thereby increase genetic diversity [PMID: 12831470]. In most flowering plants, SI systems are controlled by a single multi-allelic locus termed the S-locus. Other members of this group do not play a role in SI [PMID: 8819313], and some members are from self-compatible plants such as Oryza sativa (Rice) and Arabidopsis thaliana (Mouse-ear cress), neither of which possess the SI response. P93068 and O23743 from Brassica oleracea (Wild cabbage), as well as O81905 from A. thaliana, are reported to possibly have overlapping roles in both defence and development [PMID: 9014364, PMID: 11814694].

The proteins in this family contain an extracellular D-mannose-binding lectin domain (IPR001480), an S-locus glycoprotein family domain (IPR000858), a PAN domain, and an intracellular kinase domain (IPR000719).
