Cryptic family protein 1B is a protein that in humans is encoded by the CFC1B gene.[2][3] Cryptic family protein 1B acts as a receptor for the TGF beta signaling pathway.

Cryptic is a glycosylphosphatidylinositol-anchored coreceptor that binds nodal and the activin type I (ALK)-4 receptor (ALK4).[4]

Contents

Structure

Cripto is composed of two adjacent cysteine-rich motifs, the EGF-like and the CFC, of a N-terminal signal peptide and of a C-terminal hydrophobic region attached by a GPI anchor.[1]

NMR data confirm that the CFC domain has a C1-C4, C2-C6, C3-C5 disulfide pattern and show that structures are rather flexible and globally extended, with three noncanonical antiparallel strands.[1]

Clinical significance

CFC1B has oncogene potential.[1] Furthermore the cryptic protein is highly overexpressed in many tumors.[1]

Cripto is one of the key regulators of embryonic stem cells differentiation into cardiomyocyte vs neuronal fate.[5]
