Background Information
BBS4 (Bardet-Biedl syndrome protein 4) is one of the early BBS proteins discovered, with 35 mutations reported to cause the BBS phenotype (PMID: 26762677). BBS4 undergoes localization to the centriolar satellites of centrosomes and basal body of primary cilia, where it takes part in recruiting cargo to centriolar satellites and allowing the formation of a functional centrosomal microtubule organizing center (MTOC) (PMID: 25860617). Some research has found that BBS4 expression in humans during the development of CNS and sensory organs, concerning the cardinal clinical signs of BBS (PMID: 33860840).

Reviews
What customers say
The single review for this product (rated 4/5) describes a Western Blot experiment on HEK293T cells using a 1:1,000 dilution. The reviewer detected one band above the 47 kDa marker, consistent with the expected BBS4 size of 50–60 kDa, but also observed a much stronger, unexpected band just below the 20 kDa marker, suggesting some non-specific binding at lower molecular weights.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
