These results indicate that ALK3 phosphorylates PAWS1 predominantly at Ser610 but can also phosphorylate at Ser614 and Ser616 in vitro. |Here, we report the discovery and characterization of PAWS1/FAM83G as a novel SMAD1 interactor. PAWS1 forms a complex with SMAD1 in a SMAD4-independent manner, and BMP signalling induces the phosphorylation of PAWS1 through BMPR1A. The phosphorylation of PAWS1 in response to BMP is essential for activation of the SMAD4-independent BMP target genes NEDD9 and ASNS. Our findings identify PAWS1 as the first non-SMAD substrate for type I BMP receptor kinases and as a novel player in the BMP pathway. |

The expression of CA-BMPr1A and CA-BMPr1B mRNA was confirmed by RT-PCR using appropriate primers to distinguish expression of the constitutively active receptors from endogenous BMP receptors; specific antibodies for these receptors were not available. However, the functional effects of their expression, i.e., phosphorylation of Smad1/5/8 and p38 MAPK, verify overexpression of the constitutively active receptors (Fig. 3B). Thus, their overexpression provoked a substantial rise in the phosphorylation of Smad1/5/8 and p38 MAPK, known downstream phosphorylated intermediates in the BMP signaling pathway (Fig. 3B) (16, 17). |

The expression of CA-BMPr1A and CA-BMPr1B mRNA was confirmed by RT-PCR using appropriate primers to distinguish expression of the constitutively active receptors from endogenous BMP receptors; specific antibodies for these receptors were not available. However, the functional effects of their expression, i.e., phosphorylation of Smad1/5/8 and p38 MAPK, verify overexpression of the constitutively active receptors (Fig. 3B). Thus, their overexpression provoked a substantial rise in the phosphorylation of Smad1/5/8 and p38 MAPK, known downstream phosphorylated intermediates in the BMP signaling pathway (Fig. 3B) (16, 17). |
