Roles of TGFβ signaling Smads in squamous cell carcinoma

open access: yesCell & Bioscience, 2011
Smad proteins are classified in different groups based on their functions in mediating transforming growth factor β (TGFβ) superfamily components. Smad1/5/8 mainly mediate bone morphogenetic proteins (BMP) pathway and Smad2/3 mainly mediate TGFβ pathway.

A novel BR-SMAD is required for larval development in barber’s pole worm Haemonchus contortus

open access: yesMicrobial Cell, 2020
SMAD proteins mediate TGF-β signaling and thereby regulate the metazoan development; however, they are poorly defined in Haemonchus contortus–a common blood-sucking parasitic nematode of small ruminants. Here, we characterized an R-SMAD family protein in

Smad proteins function as co-modulators for MEF2 transcriptional regulatory proteins [PDF]

open access: yesNucleic Acids Research, 2001
An emerging theme in transforming growth factor-ss (TGF-ss) signalling is the association of the Smad proteins with diverse groups of transcriptional regulatory proteins. Several Smad cofactors have been identified to date but the diversity of TGF-ss effects on gene transcription suggests that interactions with other co-regulators must occur.

Mechanism and Regulation of Nucleocytoplasmic Trafficking of Smad

open access: yesCell & Bioscience, 2011
Smad proteins are the intracellular mediators of transforming growth factor β (TGF-β) signaling. Smads function as transcription factors and their activities require carboxyl-terminal phosphorylation by TGF-β receptor kinases which are embedded in the ...
