ARPC1B Antibody

1. A homozygous frameshift mutation in ARPC1B (p.Val91Trpfs*30) was identified in a child with microthrombocytopenia, eosinophilia and inflammatory disease. Platelet lysates contained no ARPC1B protein and reduced Arp2/3 complex. Missense ARPC1B mutations were identified in an unrelated patient with similar symptoms and ARPC1B deficiency. ARPC1B-deficient platelets are microthrombocytes with abnormal spreading behavior. PMID: 28368018
2. A homozygous 2 bp deletion, n.c.G623DEL-TC (p.V208VfsX20), in Arp2/3 complex component ARPC1B that causes a frame shift resulting in premature termination was found in 2 brothers with hematopoietic and immunologic symptoms reminiscent of Wiskott-Aldrich syndrome. Wild-type ARPC1B but not mutant was able to rescue a deficiency in a zebrafish model. ARPC1B expression is restricted to hematopoietic cells. PMID: 29127144
3. This study identified two low-frequency nonsynonymous variants at FKBPL (rs200847762, OR = 0.34, 95% CI = 0.20-0.57, P = 4.31 x 10-5) and ARPC1B (rs1045012, OR = 0.56, 95% CI = 0.43-0.74, P = 4.30 x 10-5) associated with breast cancer risk. PMID: 27479355
4. low-expression of ARPC1B is significantly associated with LNM and advanced tumor staging whereas high expression of Cav-1 can be a prognostic indicator for poor prognosis in OSCC patients. PMID: 26138391
5. p41-Arc activates a senescence program in p53- and Rb-independent ways. PMID: 21628992
6. Arpc1b is both a physiological activator and substrate of Aurora A kinase and these interactions help to maintain mitotic integrity in mammalian cells. PMID: 20603326
7. INSIG1 and p41 Arp2/3 complex (p41-Arc)reduced expression might be involved in gastric cancer development or progression PMID: 12115587
8. Phosphorylation of p41-ARC by p21-activated kinase 1. PMID: 14749719
9. From the analysis of the different radio-sensitivity cancer cell lines, the Arpc1b gene was selected as a prediction marker gene for sensitivity of CMM to radiotherapy. PMID: 16723437
