S. frugiperda insect ovarian cell line Sf 21-derived recombinant mouse TGF‑ beta RI/ALK-5 Ala21-Glu121 Accession # BAA05023
Specificity
Detects mouse TGF‑ beta RI/ALK-5 in direct ELISAs and Western blots. In direct ELISAs and Western blots, this antibody shows approximately 20‑25% cross-reactivity with recombinant human (rh) TGF-beta RI and no cross-reactivity with recombinant rat MIS RII, rhTGF-beta RII, rhTGF‑ beta RIIb, or rhTGF‑ beta RIII.

Background
Most cell types express three sizes of receptors for TGF-beta . These are designated Type I (53 kDa), Type II (70-85 kDa), and Type III (250-350 kDa). The Type III receptor, a proteoglycan that exists in membrane-bound and soluble forms, binds TGF-beta 1, TGF-beta 2, and TGF-beta 3 but does not appear to be involved in signal transduction. The Type II receptor is a membrane-bound serine/threonine kinase that binds TGF-beta 1 and TGF-beta 3 with high affinity and TGF-beta 2 with a much lower affinity. The Type I receptor, originally known as ALK-5 (Activin receptor‑like kinase) is also a membrane-bound serine/threonine kinase that apparently requires the presence of the Type II receptor to bind TGF-beta . Current evidence suggests that signal transduction requires the cytoplasmic domains of both the Type I and Type II receptors.
