SUPPLEMENTARY INFORMATION:
Antibodies and Antisera Recognizing Members of the ArfGap Family of Proteins
Description of Technology
The technology involves antibodies and antisera that recognize members of the ArfGap protein family, including the following proteins:
• ACAP1, which is related to ASAP1, a putative oncogene that regulates cancer cell invasion into normal tissues. ACAP1 regulates integrins, which are critical for cell movement associated with cancer cell invasion and is a target of the oncogene Akt.
• ACAP2, which is related to ASAP1, a putative oncogene that regulates cancer cell invasion into normal tissues.
• AGAP2 (also known as PIKE-A), ASAP1 (also called AMAP1 and DDEFl), and ASAP3 all exhibit elevated expression levels in cancer cells compared to non-transformed cells and as putative oncogenes have been implicated as regulators of cancer cell invasion into normal tissues and contributors to brain, eye and breast, and liver cancers, respectively.
• ARAP1 (also called Centaurin Delta 2), which has been implicated as a regulator of epidermal growth factor receptor, which plays important roles in several malignancies.
• ARAP2 (also called Centaurin Delta 1), GIT1 and GIT2; all three of which have been implicated as regulators of cell migration required for cancer cell invasion into normal tissues and metastasis.
• ARAP3, a target of the Src oncogene, has been implicated as a regulator of cell movement and signaling.
• ArfGAP1, which is critical to cell function, including protein trafficking.
• ASAP2 (also known as PAG3 or as Pap in the 1999 Molecular and Cellular Biology publication), is highly related to ASAP1, which has been implicated as a regulator of cancer cell invasion into normal tissues.
The table below summarizes the antibodies and antisera available against different ArfGap proteins. Each material has been raised or generated to the peptide sequence listed.
