25704993 Ropporin gene expression is related to the sperm motility. Its abnormal expression in the sperm of asthenozoospermic men with varicocele is associated with impaired sperm motility that is improved after varicocelectomy.
22021175 Lack of ROPN1 had no effect on ciliary motility.
21654522 We suggest that ropporin is a promising target for MM immunotherapy, as we were able to generate human leukocyte antigen class I-restricted cytotoxic lymphocytes able to kill autologous MM cells.
21240291 CABYR variants form a complex not only with the scaffolding protein AKAP3 but also with another RII-like domain-containing protein in the sperm fibrous sheath.
20705794 ropporin was predominantly expressed in round spermatids in human testis, and located in the principal piece and end piece of spermatozoa flagella. Expression level of ropporin was significantly lower in asthenozoospermic men than in normozoospermic men.
20107840 One SNP (rs4499545) in the ROPN1-KALRN intergenic region showed significant allelic and genotypic association with ischemic stroke risk.
20107840 Observational study of gene-disease association. (HuGE Navigator)
17551920 Ropporin gene expression in tumor cells is associated with the presence of high titer IgG antibodies against Ropporin, suggesting the in vivo translation of the mRNA into protein and the immunogenicity of the protein to the autologous hosts.
