| Post Translational Modifications | Ubiquitinated by RNFT2 in response to IL3. Ubiquitination leads ligand-induced degradation by the proteasome. Ubiquitinated by RNF128 via 'Lys-27'-linked polyubiquitination, facilitating its degradation through the lysosomal pathway. |
| Function | Cell surface receptor for IL3 expressed on hematopoietic progenitor cells, monocytes and B-lymphocytes that controls the production and differentiation of hematopoietic progenitor cells into lineage-restricted cells. Ligand stimulation rapidly induces hetrodimerization with IL3RB, phosphorylation and enzyme activity of effector proteins such as JAK2 and PI3K that play a role in signaling cell proliferation and differentiation. Activation of JAK2 leads to STAT5-mediated transcriptional program. |
