MARCH9, a member of the RING-CH family of transmembrane E3 ubiquitin ligases, down-regulates CD4, major histocompatibility complex-I (MHC), and ICAM-1 in lymphoid cells. To identify novel MARCH9 substrates, we used high throughput flow cytometry and quantitative mass spectrometry by stable isotope labeling by amino acids in cell culture (SILAC) to determine the differential expression of plasma membrane proteins in a MARCH9-expressing B cell line. This combined approach identified 13 potential new MARCH9 targets. |

We also determined that recombinant PTPRJ directly dephosphorylates the cytoplasmic tyrosine residues of purified full-length CEACAM3 and recognizes synthetic CEACAM3-derived phospho-peptides as substrates.|We show depletion of PTPRJ results in a gain-of-function phenotype, while overexpression of a constitutively active PTPRJ phosphatase strongly reduces bacterial uptake via CEACAM3. |

Taken together, the described findings supported the notion that FLT3 ITD causes reduced DEP-1 activity compared with cells expressing WT FLT3 rather than alterations in mRNA or protein levels. |

As reduction of pi3k activity by cd148 or shp-1 [32] is not large (2540%), it is likely that these ptps may function as modulators of the pi3k pathway rather than suppressors. |

Because c-CBL’s activation is achieved via tyrosine phosphorylation, we tested the effect of DEP-1 on modification of a major site of phosphorylation, namely tyro- sine 731. Upon DEP-1 overexpression, c-CBL displayed reduced phosphorylation on this site compared to control cells (Figure 7B). This result offers a mechanism by which DEP-1 affects EGFR trafficking: by dephosphorylating EGFR, and possibly also SRC family kinases involved in phosphoryla- tion of c-CBL [31, 32], DEP-1 reduces activation of c-CBL and its recruitment to the activated EGFR, hence inhibiting subsequent receptor internalization and degradation. |
