| | RALFL19 | Protein RALF-like 19; Cell signaling peptide that may regulate plant stress, growth, and development. Mediates a rapid alkalinization of extracellular space by mediating a transient increase in the cytoplasmic Ca(2+) concentration leading to a calcium-dependent signaling events through a cell surface receptor and a concomitant activation of some intracellular mitogen-activated protein kinases (By similarity). (110 aa) |
| | LLG2 | GPI-anchored protein LLG2. (163 aa) |
| | KIP | Protein KINKY POLLEN; May be involved in membrane trafficking (By similarity). Required for tip growth in pollen tubes and root hairs. Belongs to the SABRE family. (2587 aa) |
| | AT5G46220.1 | Transmembrane protein (DUF616). (462 aa) |
