Descriptions

ACTN2 is F-actin cross-linking protein. Interaction with the Z-repeat of Titin protein via the C-terminal region of ACTN2 targets ACTN2 to Z-disk. Full-length ACTN2 does not bind Z-repeats. ACTN2 has a region between ABD and R1 acting as a pseudo-Z-repeat, and this region prevents the binding of ACTN2 to the Z-repeat of Titin protein.

5 GO annotations of cellular component

Name Definition
cell junction A cellular component that forms a specialized region of connection between two or more cells, or between a cell and the extracellular matrix, or between two membrane-bound components of a cell, such as flagella.
cell projection A prolongation or process extending from a cell, e.g. a flagellum or axon.
cortical actin cytoskeleton The portion of the actin cytoskeleton, comprising filamentous actin and associated proteins, that lies just beneath the plasma membrane.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
Z disc Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

2 GO annotations of molecular function

Name Definition
actin filament binding Binding to an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
calcium ion binding Binding to a calcium ion (Ca2+).

2 GO annotations of biological process

Name Definition
actin cytoskeleton organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.
muscle cell development The process whose specific outcome is the progression of a muscle cell over time, from its formation to the mature structure. Muscle cell development does not include the steps involved in committing an unspecified cell to the muscle cell fate.
