ALK-6
ALK-6, also known as CDw293 (cluster of differentiation w293), is a member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases. BMPs are involved in endochondral bone formation and embryogenesis, transducing signals through the formation of heteromeric complexes of 2 types BMP receptors: type I receptors (50-55 kD) and type II receptors (70-80 kD). Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators[1]. ALK-6 is the receptor for BMP-7/OP-1 and GDF-5, positively regulates chondrocyte differentiation through GDF-5 interaction[2]. ALK-6 signaling is also controlled by SCUBE3, a BMP-2/BMP-4 co-receptor, recruits the BMP receptor complexes into raft microdomains, and positively modulates signaling possibly by augmenting the specific interactions between BMPs and BMP type I receptors[3]. ALK-6 involves in controlling growth, morphogenesis, and bone and teeth development through modulation of BMP signaling, is essential for chondrogenesis in vivo, while BMPR1A/ALK-3 and ALK-6 have overlapping functions during early chondrogenesis[4]. ALK-6/GDF-9/BMP-15 signals play a key role in prolificacy. ALK-6 and GDF-9 are widely expressed in 20 tissues with highest in ovary, while BMP-15 gene was expressed exclusively in ovary and pituitary[5]. The sequences of ALK-6 are highly conserved among different species, and the sequence of human shares a high similarity with rat (98.21%) and mouse (98.21%), respectively.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
