Membrane protein, palmitoylated 1, 55kDa

38-kDa, MPPI, erythrocyte membrane protein-1, FKBP38
This gene encodes the prototype of the membrane-associated guanylate kinase (MAGUK) family proteins. MAGUKs interact with the cytoskeleton and regulate cell proliferation, signaling pathways, and intercellular junctions. The encoded protein is an extensively palmitoylated membrane phosphoprotein containing a PDZ domain, a Src homology 3 (SH3) motif, and a guanylate kinase domain. This gene product interacts with various cytoskeletal proteins and cell junctional proteins in different tissue and cell types, and may be involved in the regulation of cell shape, hair cell development, neural patterning of the retina, and apico-basal polarity and tumor suppression pathways in non-erythroid cells. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009] (from NCBI)

Bhavesh et al., Mumbai, India. In Sci Rep, Dec 2014
The knob associated histidine rich protein (KAHRP) is indispensable to knob formation and has been implicated in the recruitment and tethering of P. falciparum erythrocyte membrane protein-1 (PfEMP1) by binding to its cytoplasmic domain termed VARC.
Tetratricopeptide Repeat Domain 9A Negatively Regulates Estrogen Receptor Alpha Activity.
New
Lin et al., Singapore, Singapore. In Int J Biol Sci, Dec 2014
Although TTC9A does not bind to ERα or its chaperone protein Hsp90 directly, TTC9A strongly interacts with FKBP38 and FKBP51, both of which interact with ERα and Hsp90 and modulate ERα activity.

Review
Dass et al., Australia. In J Pharm Pharmacol, 2012
FKBP-38 is a binding protein that has been discovered to be upregulated in highly aggressive cancers and binds to Bcl-2 rather than the pro-apoptotics to induce a state of hyper-mitosis.
