four-way junction helicase activity

Unwinding a DNA helix of DNA containing four-way junctions, including Holliday junctions, driven by ATP hydrolysis.

four-way junction DNA binding

Binding to a DNA segment containing four-way junctions, also known as Holliday junctions, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices.

open form four-way junction DNA binding

Binding to a DNA segment containing the open form of a four-way junction, also known as a Holliday junction, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. The open form of a four-way junction can be diagrammed without any of the strands crossing over.

crossed form four-way junction DNA binding

Binding to a DNA segment containing the crossed form of a four-way junction, also known as a Holliday junction, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices. The crossed form of a four-way junction cannot be diagrammed without any of the strands crossing over, and instead contains a single crossover between two of the strands.

heart contraction

The multicellular organismal process in which the heart decreases in volume in a characteristic way to propel blood through the body.

obsolete interfibrillar mitochondrion

OBSOLETE. A mitochondrion that occurs in between fibrils of striated muscle cells and responds in distinct ways to physiological triggers.

obsolete subsarcolemmal mitochondrion

OBSOLETE. A mitochondrion that occurs adjacent to the sarcolemma in striated muscle cells and responds in distinct ways to physiological triggers.

protein-RNA adaptor activity

The binding activity of a protein that brings together another protein and an RNA, permitting those molecules to function in a coordinated way.

kinetochore adaptor activity

The binding activity of a protein that brings the kinetochore and another molecule into contact, permitting those molecules to function in a coordinated way.

protein-tRNA adaptor activity

The binding activity of a protein that brings together another protein and a tRNA, permitting those molecules to function in a coordinated way.
