HGNC Approved Gene Symbol: RNASE3
Cytogenetic location: 14q11.2 Genomic coordinates (GRCh38) : 14:20,891,385-20,892,348 (from NCBI)
Eosinophil cationic protein (ECP) is a small, basic protein found in the matrix of the large specific granule of the eosinophil that has cytotoxic, helminthotoxic, and ribonuclease activity. It is a member of the ribonuclease multigene family (summary by Rosenberg et al., 1989).
Rosenberg et al. (1989) isolated a full-length cDNA clone for eosinophil cationic protein. ECP encodes a deduced mature protein of 133 amino acids with an N-terminal leader sequence of 27 amino acids. The mature protein has a calculated molecular mass of 15.6 kD and shares 66% sequence identity with eosinophil-derived neuroxin (RNASE2; 131410).
Hamann et al. (1990) demonstrated remarkable similarities of eosinophil-derived neurotoxin protein and eosinophil cationic protein in noncoding sequences, introns, and flanking regions, as well as the previously known coding regions. A single intron in the 5-prime untranslated region and an intronless coding region appear to be features common to many members of the RNase gene superfamily.
Hamann et al. (1990) mapped the RNASE2 and RANASE23 genes to chromosome 14q24-q31 by a combination of analysis of somatic cell hybrids and in situ hybridization. Mastrianni et al. (1992) confirmed the assignment of these genes to chromosome 14 by Southern analysis of DNAs from mouse-human cell hybrids. They commented on the fact that another eosinophil granule protein is encoded by a gene on chromosome 19 (CLC; 153310) and yet another, eosinophil peroxidase (EPX; 131399), by a gene on chromosome 17.

Dear OMIM User,
To ensure long-term funding for the OMIM project, we have diversified our revenue stream. We are determined to keep this website freely accessible. Unfortunately, it is not free to produce. Expert curators review the literature and organize it to facilitate your work. Over 90% of the OMIM's operating expenses go to salary support for MD and PhD science writers and biocurators. Please join your colleagues by making a donation now and again in the future. Donations are an important component of our efforts to ensure long-term funding to provide you the information that you need at your fingertips.
Thank you in advance for your generous support,
