The haematopoietic cytokine thrombopoietin (Tpo) is the primary regulator of megakaryocyte and platelet numbers and is required for maintenance of the haematopoetic stem cell compartment. Tpo is a heavily glycosylated, hepatocyte-derived cytokine which functions by binding to its receptor (TpoR) on ...

Structure of the TPOR complex guides design of analogs that bias hematopoiesis
Transient abnormal myelopoiesis (TAM) is a human myeloid leukemia that occurs in newborns with Trisomy 21, who acquire mutations in the transcription factor GATA1. TAM originates in the fetal liver but spontaneously regresses as hemopoiesis transitions from fetal liver to postnatal bone marrow, unle...

Pathologic TPO-induced TPOR-CSF2RB signaling mediates Down syndrome abnormal myelopoiesis due to GATA1 mutant-dependent CSF2RB overexpression [CUT&Tag]
Calreticulin (CALR) is a master lectin chaperone that guides the proper folding of integral membrane proteins in the endoplasmic reticulum. In healthy cells, CALR transiently and non-specifically interacts with thousands of immature N-glycosylated proteins through its N-terminal glycan-binding domai...

Class I cytokine receptors such as Thrombopoietin receptor (MPL) are dimers, but it is unclear whether remodeling receptor dimer topology is a viable strategy to "tune" signaling output. We utilized diabodies (DA) as surrogate ligands in a prototypical dimeric receptor-ligand system, the cytokine Th...
