[A new family of proteins with high activity for heparin and regulated by retinoic acid].
An heparin binding protein (RIHB) was purified from chick embryos. Essentially expressed during early embryogenesis it is mainly localized within basement membranes. Its synthesis and that of the RIHB mRNA are induced by retinoic acid in chicken myoblasts cell culture. This protein belongs to the same family that HBGAM or Pleiotropin and MK protein two other heparin binding proteins exhibiting growth and/or neurotrophic activities.
