The EFCAB7 Antibody, Biotin conjugated is a specialized immunological reagent designed for detecting the EFCAB7 protein in research applications. EFCAB7 (EF-Hand Calcium-Binding Domain-Containing Protein 7) is a critical component of the EvC complex, which regulates Hedgehog (Hh) signaling pathways essential for embryonic development and ciliary function . This antibody’s biotin conjugation enhances its utility in assays requiring signal amplification, such as ELISA and Western blotting .
4.1. Role in Hedgehog Signaling
EFCAB7 interacts with IQCE to anchor the EVC-EVC2 complex at the base of primary cilia, a critical site for Hh signaling . Depletion of EFCAB7 disrupts this localization, impairing GLI2 activation and mimicking Weyers syndrome phenotypes .
4.2. Genetic Disorders
Homozygous frameshift mutations in EFCAB7 (e.g., c.830delG; p.(Gly277Valfs*5)) have been linked to nonsyndromic postaxial polydactyly, underscoring its role in limb development .
4.3. Ciliary Expression
EFCAB7 localizes to the EvC zone of primary cilia, where it regulates SMO-GLI signaling . Knockout models exhibit auditory defects and reduced ciliary protein levels .
