ABCA13 Membrane Protein Introduction

Introduction of ABCA13

ABCA13 encoded by ABCA13 gene is a member of the superfamily of ATP-binding cassette (ABC) transporters which transport various molecules across extra- and intracellular membranes. There are seven subfamilies in ABC superfamily named as ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White, respectively. ABCA13 protein is the largest ABC transporter protein found so far in human, with 5,058 amino acids and more than 450 kDa molecular weight. Like other ABC transporters, ABCA13 contains 12 or more membrane-spanning domains forming a single central chamber, two large extracellular domains, and two nucleotide binding domains.

Function of ABCA13 Membrane Protein

ABCA13 is a typical member of ABC1 subfamily, with high homology to ABCA1 (51%), ABCA4 (51%), and ABCA7 (50%). Although the transport substrate of ABCA13 is not clear, ABCA13 is predicted to transport lipid molecules due to its high similarity to other members of ABC1 subfamily. Recent studies have shown that ABCA13 is present in the brain and plays a key role in the normal function of brain. The variants of ABCA13 may be involved in many neurological disorders such as schizophrenia, bipolar disorder, and depression. Moreover, ABCA13 may be associated with the progression of many cancers. It has reported that ABCA13 serves as an independent prognostic marker for diagnosis of glioblastoma. And ABCA13 also acts as a novel marker of poor outcome in pre-chemotherapy serous carcinoma effusions and its expression is significantly associated with the shorter over overall survival. In addition, the high levels of ABCA13 are found in blood-derived cells indicating it may play a role in the hematopoiesis. Now, the functions of ABCA13 is not exactly known. So further studies are required to investigate the functions of ABCA13 protein.

Application of ABCA13 Membrane Protein in Literature

1. Dréan A., et al. Correction to: ATP binding cassette (ABC) transporters: expression and clinical value in glioblastoma. Journal of Neuro-Oncology. 2018, 138(3): 479-486. PubMed ID: 29520610
   
   

   The study shows that the expression of ABCA13 is a novel and independent prognostic biomarker in diagnosed clinical value in glioblastoma patients.

   The study finds a lot of metastasis driver genes in the breast cancer progression mainly including DCC, ABCA13, TIAM2, CREBBP, BCL6B and ZNF185 genes.

   The study builds a model of dABCA (high homology to human ABC13 genes) knockdown flies used for the ABC13 physiological function in autism spectrum disorder. Moreover, dABCA has been suggested to regulate the formation and/or maintenance of presynaptic terminals of motor neurons.

   The study indicates that the variants of ABCA13 gene may be a genetic risk factor for both major depressive disorder and schizophrenia in the Han Chinese population.

   The study shows that ABCA13 amplification can be regarded as a promising marker for forecasting lymph node metastasis after early gastric cancer resection. Moreover, RTEL1 and ABCA13 synergistic effect may be used to predict the advanced staging of gastric cancer patients.
