Recombinant Anti-ENAH/MENA antibody [EPR5660] (ab124685)

Ena/VASP proteins are actin-associated proteins involved in a range of processes dependent on cytoskeleton remodeling and cell polarity such as axon guidance and lamellipodial and filopodial dynamics in migrating cells. ENAH induces the formation of F-actin rich outgrowths in fibroblasts. Acts synergistically with BAIAP2-alpha and downstream of NTN1 to promote filipodia formation. Required for the actin-based mobility of Listeria monocytogenes.

Expressed in myoepithelia of parotid, breast, bronchial glands and sweat glands. Expressed in colon-rectum muscolaris mucosae epithelium, pancreas acinar ductal epithelium, endometrium epithelium, prostate fibromuscolar stroma and placenta vascular media. Overexpressed in a majority of breast cancer cell lines and primary breast tumor lesions.

Belongs to the Ena/VASP family.
Contains 1 WH1 domain.

The EVH2 domain is comprised of 3 regions. Block A is a thymosin-like domain required for G-actin binding. The KLKR motif within this block is essential for the G-actin binding and for actin polymerization. Block B is required for F-actin binding and subcellular location, and Block C for tetramerization.

NTN1-induced PKA phosphorylation on Ser-265 directly parallels the formation of filopodial protrusions.
Phosphorylated upon DNA damage, probably by ATM or ATR.

Cytoplasm. Cytoplasm > cytoskeleton. Cell projection > lamellipodium. Cell projection > filopodium. Cell junction > synapse. Cell junction > focal adhesion. Targeted to the leading edge of lamellipodia and filopodia by MRL family members. Colocalizes at filopodial tips with a number of other proteins including vinculin and zyxlin. Colocalizes with N-WASP at the leading edge. Colocalizes with GPHN and PFN at synapses.
