Designing a Western blot for ARPC1B? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.
Open the ARPC1B Western Blot GuideFacts about Actin-related protein 2/3 complex subunit 1B.
Besides its function in the cytoplasmic cytoskeleton, the Arp2/3 complex also promotes actin polymerization in the nucleus, thereby regulating gene transcription and repair of damaged DNA (PubMed:29925947). The Arp2/3 complex promotes homologous recombination (HR) repair in response to DNA damage by promoting nuclear actin polymerization, resulting in drive motility of double-strand breaks (DSBs) (PubMed:29925947).
