The invention provides a single-stranded nucleic acid capable of inhibiting expression of a target gene having a delivery function. The nucleic acid contains, from the 5′-side to the 3′-side, a 5′-side region (Xc), a linker region (Lx), an inner region (Z), a linker region (Ly) and a 3′-side region (Yc) in this order, wherein the inner region (Z) is constituted by linkage of the inner 5′-side region (X) and the inner 3′-side region (Y), the 5′-side region (Xc) is complementary to the inner 5′-side region (X), the 3′-side region (Yc) is complementary to the inner 3′-side region (Y), at least one of the inner region (Z), the 5′-side region (Xc) and the 3′-side region (Yc) comprises an expression inhibitory sequence that inhibits expression of a target gene, and at least one of the 5′-terminus, the 3′-terminus, the linker region (Lx) and the linker region (Ly) is bound to a bio-related substance.
本发明提供了一种单链核酸,具有抑制具有递送功能的靶基因表达的能力。该核酸包含从5'-端到3'-端的5'-端区域(Xc)、连接区域(Lx)、内部区域(Z)、连接区域(Ly)和3'-端区域(Yc),其中内部区域(Z)由内部5'-端区域(X)和内部3'-端区域(Y)的连接构成,5'-端区域(Xc)与内部5'-端区域(X)互补,3'-端区域(Yc)与内部3'-端区域(Y)互补,至少其中之一的内部区域(Z)、5'-端区域(Xc)和3'-端区域(Yc)包含抑制靶基因表达的表达抑制序列,而5'-端、3'-端、连接区域(Lx)和连接区域(Ly)中至少有一个与生物相关物质结合。
