Leucine-Rich Repeat-Containing Protein 26 (LRRC26) Antibody
Por favor contáctenos para obtener información detallada sobre el precio y disponibilidad.
Description
Auxiliary protein of the large-conductance, voltage and calcium-activated potassium channel (BK alpha). Required for the conversion of BK alpha channels from a high-voltage to a low-voltage activated channel type in non-excitable cells. These are characterized by negative membrane voltages and constant low levels of calcium.

Descripción
LRRC26 is a leucine-rich repeat-containing protein that functions as a regulatory subunit of large-conductance calcium-activated potassium (BK) channels, modulating their gating properties and activity. LRRC26 enhances BK channel sensitivity to calcium, allowing activation at lower intracellular calcium concentrations and contributing to processes like membrane potential regulation, ion homeostasis, and smooth muscle relaxation. It is predominantly expressed in tissues such as salivary glands, prostate, and immune cells, where it regulates fluid secretion, smooth muscle tone, and immune cell activation. LRRC26 also plays a role in modulating cell proliferation and survival, particularly in tumor cells, where it promotes BK channel activity to support cell cycle progression and growth. Dysregulation of LRRC26 has been linked to cancer progression, particularly in prostate and breast cancer, where it enhances potassium efflux and supports cell proliferation and migration. Functional studies reveal its importance in fine-tuning BK channel activity, maintaining ionic balance, and regulating cellular excitability under physiological and pathological conditions.
