<p>This subsection of the 'Family and domains' section provides general information on the biological role of a domain.

Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

PH domain binds phospholipids including phosphatidic acid, phosphatidylinositol 3-phosphate, phosphatidylinositol 3,5-bisphosphate (PIP2) and phosphatidylinositol 3,4,5-trisphosphate (PIP3). May mediate ACAP1-binding to PIP2 or PIP3 containing membranes. Only one PH domain of one ACAP1 dimer inserts into the membrane, while the other PH domain acts primaryly to interact with adjacent ACAP1 dimers (By similarity).By similarity
The BAR domain mediates homodimerization, it can neither bind membrane nor impart curvature, but instead requires the neighboring PH domain to achieve these functions (By similarity).By similarity

<p>The checksum is a form of redundancy check that is calculated from the sequence.
