1. A composition comprising an engineered and/or non-naturally occurring complex comprising:
(a) a CasY polypeptide, or a nucleic acid encoding said CasY polypeptide, wherein the CasY polypeptide comprises an amino acid sequence having 97% or more amino acid sequence identity to the amino acid sequence set forth in any one of SEQ ID NOs: 1-2, 4, and 57;
(b) a CasY guide RNA, or a nucleic acid encoding said CasY guide RNA, wherein said CasY guide RNA comprises a guide sequence that is complementary to a target sequence of a target nucleic acid, and comprises a region that can bind to the CasY polypeptide; and
(c) a CasY transactivating noncoding RNA (trancRNA), or a nucleic acid encoding said CasY trancRNA.
