Mouse TGF-beta  RI/ALK-5 APC-conjugated Antibody Summary

Species Reactivity
Detect mouse TGF-beta RI/ALK-5 in flow cytometry. Although this clone detects human and mouse TGF-beta RI/ALK-5 in Western blots, positive results have not been observed on human TGF-beta RI/ALK-5 in flow cytometry. In direct ELISAs and Western blots, this antibody shows no cross-reactivity with rrMIS RII, rhTGF‑ beta  RII, rhTGF‑ beta  RIIb, or rhTGF‑ beta  RIII.

Background: TGF-beta RI/ALK-5

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.
