Modified yeast-two-hybrid system to identify proteins interacting with the growth factor progranulin.

ABSTRACT: Progranulin (PGRN), also known as granulin epithelin precursor (GEP), is a 593-amino-acid autocrine growth factor. PGRN is known to play a critical role in a variety of physiologic and disease processes, including early embryogenesis, wound healing, inflammation, and host defense. PGRN also functions as a neurotrophic factor, and mutations in the PGRN gene resulting in partial loss of the PGRN protein cause frontotemporal dementia. Our recent studies have led to the isolation of PGRN as an important regulator of cartilage development and degradation. Although PGRN, discovered nearly two decades ago, plays crucial roles in multiple physiological and pathological conditions, efforts to exploit the actions of PGRN and understand the mechanisms involved have been significantly hampered by our
