Anti-GPD1L Antibody Picoband® Fluoro488 Conjugated

GPD1L is a human gene. It is mapped to 3p22.3. The protein encoded by this gene contains a glycerol-3-phosphate dehydrogenase (NAD+) motif and shares 72% sequence identity with GPD1. The encoded protein is found in the cytoplasm, associated with the plasma membrane, where it binds the sodium channel, voltage-gated, type V, alpha subunit (SCN5A) . Defects in this gene are a cause of Brugada syndrome type 2 (BRS2) as well as sudden infant death syndrome (SIDS) .

Plays a role in regulating cardiac sodium current; decreased enzymatic activity with resulting increased levels of glycerol 3-phosphate activating the DPD1L-dependent SCN5A phosphorylation pathway, may ultimately lead to decreased sodium current; cardiac sodium current may also be reduced due to alterations of NAD (H) balance induced by DPD1L.
