snrp-27(az56) is a M141T missense allele with semi-dominant suppression of e936. No phenotype on its own. az56 is a CRISPR-induced mutation mimicking a known suppressor of unc-73(e936). This allele activates many dozens of alternative 5' splice sites in an RNA-seq experiment. snrp-27 is a component of the tri-snRNP and pre-B spliceosomal complexes. Reference: Zahler AM, et al.

SNU-66 H765G substitution. No obvious morphological or growth phenotypes were observed. az160 mutation disrupts SNU-66(H765)/SNRP-27(M141) interaction, affecting alternative 5' splice site usage. Worm SNU-66(H765) and SNRP-27(M141) are homologous to human preB spliceosome components snu66(H734) and snrnp27(M141), respectively. Reference: Sarka K, et al. 2024. In submission.
