Events
Background: Bone morphogenetic proteins (BMPs)
constitute a large family of signaling molecules that regulate
a wide range of critical processes including morphogenesis,
cell-fate determination, proliferation, differentiation, and
apoptosis (1,2). BMP receptors are members of the TGF-β
family of Ser/Thr kinase receptors. Ligand binding induces
multimerization, autophosphorylation, and activation of
these receptors (3-5). They subsequently phosphorylate
Smad1 at Ser463 and Ser465 in the carboxy-terminal motif
SSXS, as well as Smad5 and Smad8 at their corresponding sites. These phosphorylated Smads dimerize with the
coactivating Smad4 and translocate to the nucleus, where
they stimulate transcription of target genes (5).
MAP kinases and CDKs 8 and 9 phosphorylate residues in
the linker region of Smad1, including Ser206. The phosphorylation of Ser206 recruits Smurf1 to the linker region
and leads to the degradation of Smad1 (6). Phosphorylation
of this site also promotes Smad1 transcriptional action by
recruiting YAP to the linker region (7).
Specificity/Sensitivity: Phospho-Smad1/5 (Ser463/465)
(41D10) Rabbit mAb detects endogenous levels of Smad1
and Smad5 only when dually phosphorylated at Ser463 and
Ser465 and is also predicted to detect Smad9 (Smad8) when
phosphorylated at Ser465 and Ser467. The antibody does not
cross-react with other Smad-related proteins.
