Fibulin 4 (EFEMP2) Antibody – Rabbit Polyclonal

A large number of extracellular matrix proteins have been found to contain variations of the epidermal growth factor (EGF) domain and have been implicated in functions as diverse as blood coagulation, activation of complement and determination of cell fate during development. The protein encoded by this gene contains four EGF2 domains and six calcium-binding EGF2 domains. This gene is necessary for elastic fiber formation and connective tissue development. Defects in this gene are cause of an autosomal recessive cutis laxa syndrome. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Jan 2011]

EFEMP2: Defects in EFEMP2 are the cause of cutis laxa, autosomal recessive, type 1B (ARCL1B). A connective tissue disorder characterized by characterized by loose, hyperextensible skin with decreased resilience and elasticity leading to a premature aged appearance. Face, hands, feet, joints, and torso may be differentially affected. The clinical spectrum of autosomal recessive cutis laxa is highly heterogeneous with respect to organ involvement and severity. ARCL1B features include emphysema, lethal pulmonary artery occlusion, aortic aneurysm, cardiopulmonary insufficiency, birth fractures, arachnodactyly, and fragility of blood vessels. Belongs to the fibulin family.
